That's no reason.

Effectively, you can create a spec file in "devel" which you can
copy unmodified to older branches.

If, however, you really need to modify'n'bump an older branch only,
increase the "Release" value in the least-significant position at
the very right,

  4%{?dist} => 4%{?dist}.1 => %{?dist}.2 => and so on

but if it's just minor modifications, you better use the %fedora
macro as above.

What do you think why does Anaconda support distribution upgrades?
It has been the official upgrade method for many years (as with
old Red Hat Linux), and our users do also Yum/Apt-based dist-upgrades.
