Obsoleting the group field does imho not significantly ease its use. 
It rather makes its non-ootb use harder, because you now have to edit
two operating-system fields, without changing anything for the ootb
use.

No, it doesn't: Since it pulls in the groups field into "stuff you need
to worry about when editing your MPD service", it actually exacerbates
the issue.  Yes, the API is awkward, but it does help making mpd-
service-type self-contained.

What is "it" here: the fact that you can make a group with (system? #f)
or the error in accounts-service-type that has been demoted to a
warning?
