That is possible, sure. I think that rebuilding related packages is just
easier, there are only a few needed. Users that would like to run 3.6
before it is made available with Fedora 22 need to add a repository for
the glusterfs-3.6 packages anyway, using the same repository to provide
related packages is simple enough.

But, if there is a strong interest in having a -compat package, we can
discuss that during tomorrows (Wednesdays) meeting.
