both wheel and distlib use py_version_nodot, and the last sentence I quoted
looks provisional rather than definitive.
That's because API/ABI versioning is technically up to the individual
implementations. The PEP only mandates particular behaviour for CPython and
the implementation independent tags.
If if you want a definitive answer on that, ask the PyPy devs to write one
up.
I would have preferred to mandate behaviour based on sys.implementation,
but that still wouldn't have covered 2.x.
Cheers,
Nick.
