It's a little more than "benefit from", the default desktop install
of Ubuntu/Kubuntu leaves the user not even knowing the root password,
so it simply won't work to not pick up the distro version.

but that choice can't be made here; a significant number of
systems will not have the sudoers file configured out of the
box and users will not be able to use sudo; alternatively as
noted above on some other set of systems it's not going to
work to use su.
it's really important to maintain this abstraction level
so that the distro version can "do the right thing" and not
have the Portland work impose too many constraints.
