We do all of those things to. I still don't know why you'd think we don't.
What do you do outside of MS and ERP? Why make your team broad, if the company doesn't consider doing anything outside of the immediate scope per your other description? It's interesting to be so focused yet have a broad idea of learning. For us, broad learning makes sense because of business/IT is in our scope so anything that makes us better, is good. But if you are "we are fired if the customer changes tech" that puts you in an awkward position of having to expose to customers that they should leave you in order to provide IT guidance in cases where the product you support isn't a best fit. That's why traditionally that situation is only used by VARs.
