I’m going to include this patch in the python-team branch. We’re
looking at a massive rebuild due to #63139 anyways, as you said. In
theory there’s nothing wrong with patching setuptools like this, but
I’d like to avoid it, because that substitute* can just break silently
in the future.

Cheers,
Lars
