Part of the problem here is that there are authors publishing quite a lot of modules on CPAN who *consistently* rely on such versioning tricks - or at least have relied on those over many years. This would have meant having a package with an epoch in the double digits... which, besides simply looking weird, also brings its own can of worms.
