Sure

We shouldn't remove the group because this would induce
inconsistencies in users databases.


> What should the warning tell? Currently:
>     Warning: The primary group of bug295416 (bug295416, GID=1003)
>     will be removed, but is also the primary group of other295416

"Cannot remove group %s which is a primary group for another user"

And a dedicated exit code (not sure about this as this could break
some utilities relying on non zero exit code to check that the user
has indeed been removed)
