CPython can be embedded in applications, though, and that is why we try
to be a bit more thorough during the interpreter cleanup phase.

Indeed. My gut feeling is that proposing to not run finalizers on interpreter shutdown is a non-starter and would get the pep rejected. We've previously guaranteed that they were run unless the process dies via an unhandled signal or calls os.\_exit() in CPython.
