As Robert posted on the review:
a) pbr doesn't support epochs [yet]
b) the release team specifically decided not to epoch things.
Also you'll find that the various distros use different epoch values for
the same software, because epoch are also used to cover local blunders
in packaging and historical artifacts. That is why epochs should be
local to each packaging system and specifying it upstream is imho
