No comment.  :-)

I was assuming you knew how that worked.  $releasever is set to the
version number of the package specified by the "distroverpkg" config
file setting.  $basearch is `uname -i`.  (It should be pretty clear
that $basearch would never change.)

It doesn't have to since they don't change. :)

I don't think it does.

Most things are done for a reason.  That does not imply the reason is
good or sound.  :-)
