Regarding the publishing of “not really manylinux” wheels as manylinux on PyPI, it was assumed when rolled out initially, that folks would be good citizens and not lie
Since that’s not the case, there’s a feature for PyPI under discussion on the issue tracker to disallow uploading such wheels. To be clear, such wheels are definitely something we want to not allow. IIUC, the current blocker is someone implementing this and figuring out the timelines.
