So how do you propose to clean them up? Or let user systems trash
with unused uids/gids? The GLEP 81 only mensions some possible
tooling for cleanup. Is there an implementation available? I don't
see it within proposed patch sets.

This GLEP should not be accepted unless all necessary tools are
available including a cleanup tool.
