I might be not following correctly, but due to how filesystems/etc
work it is probably desirable to have consistent UID/GIDs as much as
reasonably possible.  Things like NFS, chroots, containers, and so on
can be a bit simpler if these are consistent, because they involve one
system having visibility into a filesystem hosted on another, and
usually in these cases the UID/GID is what is kept constant, not the
name.  (IMO UID/GID namespace is one of those areas where
Linux/POSIX/etc has some weaknesses.)

This doesn't really seem like a problem though.  Just have a table
somewhere (wiki?) to track who is using what UID/GID and encode those
defaults into the ebuild that creates those users.

Overall I like your proposal.
