It can be fairly important - if the newest package breaks something,
it's good to be able to easily install an older version, or a version
between the current version and the newest.  It's ok if a special
incantation is needed to force yum to act that way, but if the only way
to get an older package is to go directly to RPM, I think that's less
than optimal.
