Is the concern the cost of licensing and CALs...
No cost to CALs, all CAL cost already exists from the first Windows server.
CALs are per server, so if he created a separate server to run a FS only, he would need double the CALs.
CALs are NOT per server. That is completely wrong. One Windows Server CAL per user, regardless of how many servers you have. It has always been this way and is implied in the name. All vendors follow this convention.
Your statement here makes me want to question everything I've read on CALs. . .
As I've understood it, the more Windows Workloads you have, the more CALs you need to be appropriately licensed for that specific workload.
IE
File-Server - need cals for 100 people
Domain Control - Need cals for 100 peopleIgnoring "per device CALs" as an option. The math works like this.
U = Number of Users
S = Number of Windows ServersNumber of CALs needed in any environment equals U where S > 0.
It's that simple. Count up your users, that's your number of CALs if you use Windows Servers. There's nothing more to it. Everything you've ever seen should agree with this. If it wasn't like this, the cost of Windows would be impossibly high.
If you have 1 Server, 100 Users, you need 100 CALs.
If you have 10 Servers, 10 Users, you need 10 CALs.
If you have 100 Servers, 1 User, you need 1 CAL.
If you have 1,000 Servers, 10 Users, you need 10 CALs.And so forth. The server count is a red herring. Only users are counted for CALs. Only servers are counted for Server licenses.
That's the purpose for the two things being separate. If you needed one CAL per user per server then there would be no point to the server licensing as that would be overlapping and unnecessarily complex. MS would simplify things for themselves and for customers by rolling everything into a single license. They keep them separate so that they can balance the licensing.

IE regardless of how many windows servers you're running, you only need enough CALs in your organization to cover the entire user base or devices once.
Not per server. . .
Correct

So this makes sense, and it might just be a "me issue". But every workload I have ever seen (IME) has been on different Microsoft Server versions.
IE you need CALs for that version of Windows Server. . . and thus you would need tons of CALs.
Grr time to investigate.

You don't, BUT you might end up with loads of CALs. All CALs are backwards compatible, you only need everyone to be licensed for the latest version of Windows. So if you have Windows Server 2003, 2008, 2012 R2, and 2016 in your environment, and say ten of each server, and you have 20 users, you need 20 Windows Server 2016 CALs. That's all.
But, chances are, along the way someone acquired 2003 CALs, 2008 CALs, 2012 CALs, etc. because they needed them back at the time. Today, you only need the latest 2016 CALs, but you likely have the old ones lying around from historic usage.

And they only actually sell the latest version CALs. Running 2008R2 and need more CALs? Then they sell you 2016 CALs.

That's true, only the current CALs are normally available for sale at all.

Not to beat a dead horse however, the naming of CAL is a bit misleading. Client Access Licensing on it's face would lead one to believe that for every server that a client accesses a license is needed. And in reality it is exactly the opposite in that the client needs a single license to access anything on the domain.

Does it? Nothing in the name implies server. It's a license for Clients to Access, the only "per" thing mentioned is the client.

True. But do I need a CAL on my home network? No. Why? because I don't have a multitude of servers that I need access to.

You do if you have any, though. That's the "access" part of the license. Clients exist where there is a server, without the server, there is no client. So seems logical enough that no CAL is needed where there is no client.
-
Another way to think of it...
Clients are named, servers are not. This "client" has a "client access license". The resource to access is never named or listed or mentioned. It must exist, or there is no client. But the naming convention really does lead towards "per client" and aware from "per server."
A client has an access license. We'd call it a Server Access License if it was the other way around.

As mentioned before, its not a big deal to have both of those roles on the same server. I have them on one server on my current environment. I am wanting to separate them, but the company uses the FS role too much for me to be able to bring it down long enough for a couple of reboots. I could probably do it during a weekend, but just have to do it.

Who works weekends anymore? Oh Wait, I forgot what we do here.

On licensing not sure how upto date this is but remember this is how I work out out for cal's
-
@hobbit666 that’s for user vs device. These days device are nearly obsolete. When the licenses were new people were commonly sharing devices. Today most people have more than one device each.

This post is deleted! -
@scottalanmiller Agreed but it shows nicely what you were saying about the cals covering all servers
-
I like User CALs because they are easy. Count users, get that many CALs.

Worth noting... You need the amount of CALs to equal users, for a certain platform. 2012 RDS? Needs CALs. Exchange 2013? Needs CALs. Upgraded from 2012 RDS to 2016 RDS and Exchange 2013 to 2016? All new CALs.
