I think that UID/GID should transparently be preserved when copying
directories whenever possible (in particular when using /sudo:: methods
or similar).  I don't think that there is an important usage case for
"don't preserve UID/GID even if you could": it would likely imply
copying a tree and turning it into root/root possession on today's

I would like to add that before the time of disk quotas, the owner of a
file was always able to do chown/chgrp on files (this cleared the setuid
bit for security reasons, but that was it).  It was the usual way of
passing data to somebody else (and nobody other).
