The SemanticVersion in distlib is currently strict and doesn't allow x.y, but the test script which produced those results did a simplistic check for matching x.y and tacked on a .0 in that case, before deciding on a pass/fail for semver.

The "legacy" scheme (setuptools/distribute) will do that, won't it? (For some value of "good", of course.) Of course it has drawbacks, as mentioned in PEP 386: it doesn't constrain version numbers to follow a sensible scheme. Of course, to enforce any additional constraints would need PyPI metadata checks to be added, which would no doubt annoy the minority of people who name their versions like "02 Jun 2010", "pre-release", "0.1.5dev-20111031", or "0.5.0-protobuf-2.4".
