You're right, we're always taking a view that's focussed on modules
and pay less attention to the distribution and the version attached to
it. But your view is of course relevant too.

I tend to value version.pm higher now that 5.10 is out because this
means it has gained some sort of official status. In fact, the indexer
on PAUSE already uses only version.pm. But it only looks at the
version of individual modules, not the one in the distribution name.
So whatever works for you is fine. And if things fall apart, give me
shout.
