CPAN looks like it can handle 'x.y.z', at least for Pugs:
>From the Perl6::Pugs source, $VERSION for rel 6.2.13 is '6.002013':
our $VERSION = 6.002013;
That's also a very perlish-way to do it. And there are no developer
versions of Pugs, since it is always under active development. We could try
our $VERSION = 1.005002_01;
just to tag it as a developer release or release candidate, if that's what
you want; I'm neutral to that point. I don't think it's necessary to post
every RC to CPAN, though, unless you feel very strongly about it. It just
seems like more hassle than it's worth, esp. since you've been releasing
about one per week leading up to a final 1.5.2 (due soon).

As a quick response to the above, I would read 'rel. 1.5.2' as the second
patched release of the second revision (here in a developer cycle) of the
first major release. I would read 'rel 1.52' as the 52nd release of the
major release (just can't quite make it to version 2, I guess). I don't
think we can use the latter as it is just too confusing, especially since
we've adopted the 'major.minor.patch' versioning quite early on.
As for CPAN, I believe there is usually a person or group responsible for
maintaining each distribution. As Ewan seems to be the point man, you'll
have to ask him. I suppose it is possible to add more if needed

When I inquired about XML::Simple, I emailed Chris D. via his contact
information from CPAN. He let me know that adding it would be pretty easy,
so all you need to do is let him know about any errors/additions/deletions.
I think his wiki page also has some contact info.
Which reminds me, if anyone contacts him, could you make sure that
XML::Simple is added? I can't remember if it has been.
