Thanks for the interesting details.
Have to admit I entered the Python land with version 1.4
and missed the C API change from 1.1 to 1.2 completely. :-)

Getting more opinions about the idea confirms me slowly
to something like, good to discuss but not worth the change.
Because some arguments confirmed me that it is not worth
to change this. Also the marketing argument is weak and you are right
that it should not care us.

The only remaining argument is to have shorter release cycles
but I think they don't depend on the versioning scheme nor
a change in it improves this.

Looking forward to 2020 when 2.7 is out of business and
the maintenance cost can be invested in Python 4 and a faster release
