Then prove CPython wrong by making a fantastically better
implementation that uses some other form of garbage collection. The
language spec does not stipulate refcounting, and in fact very clearly
does NOT stipulate what kind of garbage collection is used, so if
refcounting is such a bad idea, you should be able to take advantage
of CPython's flaw and make something better.

Go ahead. Put your code where your mouth is.
