Do you do that now?  No.  Why not?  Because $releasever is "5" and not
"5.0" or "5.1."  And that value doesn't change.  Your installs still
roll gracefully from version to version due to the magical moving of a
symlink on the repository server.  It has nothing whatsoever to do
with $releasever changing.

It would work exactly the same way with smart.  The only real
difference is that smart doesn't have to query the version of a
package every time it runs to obtain a value that never changes.
