The official demo produces broken wheels

[antocuni]

I am not sure whether this should be considered a bug of pip, manylinux or manylinux-demo.
The TL;DR version is that with the latest manylinux image, projects which are based on manylinux-demo build and possibly uploads broken binary wheels.
See this comment on the relevant pip issue for more details:
pypa/pip#8165 (comment)

@antocuni is this still the case? Seems like the linked issue resulted in a rollback which seems like (based solely on discussion) the immediate fix.

I am in the process of writing a gigantic dockerfile that is based on manylinux-demo, which was why I was wondering.
