Yes.

I am not prepared to argue over this, especially since it appears that
Stefan is not particularly happy about the change either.

Basically, elpy enables flymake everywhere and adding

--8<---------------cut here---------------start------------->8---
# Local Variables:
# flymake-mode: nil
# End:
--8<---------------cut here---------------end--------------->8---

to every scratch pad is ugly and _does not work_.

Thanks.
