FWIW, I have a preference in favour of pinning flake8 and its dependencies to stop tests from starting failing without changes in html5lib, though preferably in combination with adding some bot to update pinned dependencies.

No problem. I've changed the PR to keep flake8 pinned, but now to the latest version. All errors are still fixed.

preferably in combination with adding some bot to update pinned dependencies.

The two bots I know about: dependabot, now part of GitHub; and pyupbot, which I hear has been a bit flaky of late.

Yeah, we use pyupbot on web-platform-tests and it seems to have been going downhill…
