Let's face it, epochs are a hack of a solution within RPM (discover
this by examining either the lack of pervasiveness of epoch support in
rpmlib, or the fact the the "epoch" field is actually a perversion of
the older RPMTAG_SERIAL functionality).  Lacking a centralized package
repository like there is with Debian, epochs in RPM packages
predominately leads to user confusion and frustration.

This isn't to say they aren't necessary, just that they suck.

That said, both of your solutions suck.  One of them requires the
packager to pervert the version field, which is supposed to represent
the upstream package version, and the other forces their hand when
dealing with the revision (release) field, which is supposed to
represent the iteration of the package generated from a given tarball.

Honestly, how hard is it for the maintainer to give an appropriate
version string, such as 1.x.90 leading up to 1.(x+1).0, instead of
forcing the packager to introduce hacks like this?

No, we didn't.

That said, it wouldn't have been that inappropriate.  The epoch is
used for situations where it's desirable to "force" (strongly
recommend) that a user back down versions, or where the upstream
version scheme changes.  In this circumstance, by switching from an
X.Y.Z scheme to X.Y.ZpreW, you've essentially done that.

It's not your job to explicitly tell packagers what to do.
