>The modus operandi of the shrinking set of people who took over CPython is to add new garbage so other implementations cannot keep up.

Ridiculous accusation bordering on paranoid.

that's a bit harsh. c++ has specification and programs still break easily by just moving to a different compiler.

Do you mean they would work like that to prevent an alternative implementation? This seems a bit far fetched.

I suppose you consider new Python features are "garbage" because you don't care about them?
