Hear ! Hear !

I've been trying to change it on FreeBSD for years.

We even discussed this again a few days ago between committers... (just
ignore the /var/mail bit, it is another issue).

I don't see the problem.
 
My point is that every non setuid/gid binary & and every directory/file
should belong to root unless there is an express need for it to belong to
someone else.
 
UUCP and man are very good examples where non-root ownership is good.
 
Having /lkm, /sbin belong to non-root is BAD.
 
As for /var/mail, I don't see the need to change to 775 bin.mail.
755 root.whatever has been working for _ages_.
 
I'd rather see mail.local/procmail as setuid root to deliver than Elm and
Mutt setgid mail.
 
The bin user is a rather bad idea in my book. It gains nothing and lessen
security.
