1. deprecated lol
2. i think it can't be run on things like AD, so for very small companies this is annoying
3. ... that's not really an admin app?
4. sure, but then i might as well switch to linux if i have to stick to cli (and i did)
5. last time i checked there were two versions, incompatible with one another, not great alternative to ansible
6. if you have hybrid and are in azure already, maybe? haven't used
I mean it's not like there are not 5 alternatives in azure/intune for every thing as well that are half baked. And 365 and azure is worse with terrible migration guides, ms graph with a combination of commands and json inputs and defaults from 2016.
It's really time for microsoft to fully commit to one thing, make it good, finish it and deprecate everything else.
