Python's versioning has worked this way since well before "semantic
versioning" was invented... so I think it's more fair to say semantic
versioning is a violation of Python ;-).

CalVer does have the nice properties that it makes a public commitment
that there will never be another "x.0"-style release, and that it
encodes some useful information into the version (maybe it would be
slightly easier to convince people to stop using 2.7 if it was "Python
2010"). But the current scheme is so ingrained in the culture at this
point that I doubt there's much appetite for fiddling with it...
