Okay, but the effect would not be different. You could only bump
%epoch for every released build of a package and/or inbetween releases
of the dist. In case of the latter, there would be a conflict with
ordinary bumps of %epoch in situations where you can't avoid that.
For the former, it reminds me of "Serial: %(date +'%Y%m%d')" in
hylafax upstream src.rpm once more, which was kind of a super-Epoch.

And in either case, it would get really ugly as we already need to
be careful with Epoch bumps that must be reflected in any explicit
Requires/Obsoletes/Conflicts in other packages.

We are glad that most packages don't set %epoch or don't change it often
if it's set already. Or else we would have continued with the old
explicit "Epoch: 0" rule from fedora.us instead of removing it from
packages in Fedora Extras.
