I agree. Ditto.

And, in contrast, I believe that the free-wheeling minor version number proposed in PEP 407 is a train wreck and PR disaster waiting to happen. I find it interesting that we can so readily agree that using the major version number in any way is impossible due to the ongoing Python 2 -> 3 transition, yet I get so much pushback on the idea that messing with the implications of changing the minor version number will unnecessarily confuse or upset users.

I spent quite a bit of time thinking about the ways people use the CPython version number, and it switched me from mildly preferring a separate version number for the standard library to being a strong opponent of increasing the rate of change for the minor version number. Anyway, the PEP now describes the user scenarios that convinced me that a separate version number for the standard library was the right way to go: http://www.python.org/dev/peps/pep-0413/#user-scenarios

Cheers, Nick.
