Sorry if this was already suggested and hastily rejected, but why do we care
at all about the reference counter of the few heavily-used immortal objects of
CPython?

I guess allowing their counter not to be carefully maintained ventures to the
slippery slopes of bad code.  Anyway, my two cents for a (very) slightly
faster and shorter code would be to be allowed never to do Py_INCREF or
Py_DECREF when we know that the object is Py_None, Py_False or Py_True.  These
three would have a dummy tp_dealloc that just resets the reference counter to
some large value if it ever reaches zero.
