IIRC the epoch was not added to the file name of archives as the epoch
will only increase when a change to the version number demands it,
leading to a new unique combination of ${name}-${version}_${revision}.

Out of curiosity, what happens when a port version does not follow the
canonical format of major.minor.revision?
