Разница есть в силу возможностей оптимизации зависимостей самим rpmbuild.

Почему бы мейнтейнерам давным-давно не обратить внимание на
предупреждения в логах сборки о неполноте межпакетных зависимостей?
В случае с нехваткой %epoch можно было бы просто выполнить
$ grep '^warning: [^ ]* dependency on [^ ]* needs Epoch'

Может быть, поднять warning до error с возможностью обратного понижения
макросом?

Как вариант.
