Basically you're saying that every admin at an MSP should have two machines - one for managing clients, and one for MSP related email/web surfing, etc.

All it takes is one absentminded click or drive-by that's completely shielded from us as we go about the day to day stuff and it's done. Game over. Say, "Bubbye".
There's always going to be that risk or one absentminded click.
Granted an Air-gapped PWA is a good way to handle it.... but so is not saving passwords in RDP files (I don't do this), and if you use an app like MobaXterm that can encrypt the files for you, use a good pass phrase.
However if your admin machine is owned, you have bigger issues to start with.

Well, the idea is that the air-gapped machine won't ever be in a situation to become compromised, is my guess. I haven't had a chance to look at the MS link Philip sent earlier.

It will be, because a human always has to use it at the end of the day. A used system is an at risk system. Less risk, certainly. There is good design and bad design. Good useage and bad useage. But any useful machine is at risk by nature of being useful.

There are several ways to implement with the simplest being the main machine having two VMs installed on it. One for day-to-day and one for client/systems management. Nothing is done on the machine itself with all designated tasks being done in their respective VM.
We have a number of laptops that came back from client refreshes. So, we're using them as our dedicated management machines. Asus makes a great external USB3 DisplayLink and DisplayPort external monitor that allows for two screens. That makes the work easier.

We do this for certain tasks, it is air gapped in that nothing can move between the main desktop and the VM. But the human is still there, of course.

This can be a great use case for small, limited machines like Raspberry Pi. Or super high power desktops that can run a lot of desktop VMs for you locally. And a place where, if you can, using Linux makes it work so much better. No limitations on count, don't need a GUI in all cases. Can run on ARM if you want.

We're getting there but not yet. The idea that's coming down the pipe is a boutique build we have designed that has everything mounted on small aluminium plate and is essentially wireless except power. It's a fun side project.

There is security leakage between VMs on a client machine for instance over clipboard.
Have a look at Qubes. https://www.qubes-os.org/
It's probably the best implementation of security separation to date.

not all have clipboards, that would be a big leak if they had that on.

Even if they do have clipboards, it is an easy enough option to disable.

Using the Hyper-V VM Console without RDS pass-through eliminates any access to the VM beyond console.

Same with KVM or whatever.
