1.5_1 compares as newer than 1.5_0, sure. But does it also compare newer
than every previous version this port has had? Given that it was
necessary to set a non-zero epoch at some point, this is far from
guaranteed.

You can't assume that everyone will be upgrading from the immediately
previous version.

Epoch is just an integer that has to be increased when a newer version
looks older to rpm-vercomp than an older one. Upstream's versioning
scheme doesn't determine the epoch.
