such a question... ;)

Safe enough, because security is managed by UID through those files, but
maybe not quite complete enough.

I would also make sure to rename their mail spool file, and do a 
find /etc -type f | xargs grep oldusername
to find places like the sudo configuration files that might reference
their usernames.  Other applications like "mysql" or "samba" might also
maintain parallel configurations for that username.

You would _still_ need to dig for references to their old username in your
mail configuration files, etc. if you tried copying to a new username to
restore all their old configurations, so I don't think that is necessarily
any safer.
