Disallowing makes it worse. Here's why:
$ perl -Mversion -E 'say version->new("1.23_45") <=> version->new("1.2345")'
-1
If the first form is specified in an installed *.pm file (as parsed
with MM->parse_version), but the second is in the META file, then the
META requirement can't be satisfied by the installed file. We *must*
allow underscore. The branch I've created is specific in that we only
allow a single underscore, though, and for v-strings, only for the
last component.

Hmm. I don't want to specify what will be assumed or else that
becomes defacto acceptable. The likely reality is that what will be
assumed is whatever version.pm does.
