Okay, I agree to you. The only thing that comes into my mind is
if someone e. g. wants to prevent users from checking out the root
of a repository the authorization file may be enhanced to have
different sorts of 'read':
'r' meaning the same as today
'r-' meaning that the user is allowed to ls and cat but not
to checkout this part of the repository
Just a thought...
