If you use heap types, you need to adjust refcounts beginning
with Python 3.8 . And since the Py_LIMITED_API uses heap types
without hiding these refcount changes by an API call,
this breaks the stable API.

But it is easily fixable by a runtime version check, or you start
over with Python 3.8 as lowest version <wink>.
