You've quoted the relevant part. Here:

So, if you drop using fedora-usermgmt, you cannot keep the relative (!)
uid 33 that has been registered for it. 33 is "amandabackup":

  $ rpm -qd setup
  /usr/share/doc/setup-2.8.36/COPYING
  /usr/share/doc/setup-2.8.36/uidgid           <-- (!)

Package "setup"'s %changelog mentions a lot of activity related to reserving
system uids/gids.

You would first need to have uid 333 registered/reserveed as a fixed uid.

Well, then it isn't following the guidelines, which mention the userdel
scriptlets. ;)

However, if the directory contains files created at run-time, the package
should not "rm -rf" those files when uninstalling, so it could remove the
empty dir.
