Note the -r. We are talking about system accounts.

I fail to see why system accounts should be shared across networks and
why there is any need to force unique UIDs on them.

IMO, system users must be local, only.

Cf. above.

The only reason for not wanting to remove accounts on package removal to
me is "accounts leaving stray files somewhere".

However, rpms should have always have control over all files it owns.
