To what? The individual packages? Maybe, but I'm not sure how useful
that would be. For example, pywin32 has been using 3-digit versions
like this forever, and I don't see them changing just on the basis of
this (but I may be wrong). PyPI seems to handle pywin32's version
fine...

I'd rather say that it's a bug in distutils2 that it complains about
perfectly valid distributions. I'd be OK with a "verify" flag/action
that checked existing installed distributions, but I see no reason for
any message (informational, warning, or whatever) when you're just
asking for a new distribution to be installed.
