For some reason SetupRequirementsError has been listed in __all__, so this __getattr__ and deprecation warning are here just to be on the safe side (and be very conservative regarding breaking changes).

Hi, I'm trying to use SetupRequirementsError to add dynamic build requirements because https://setuptools.pypa.io/en/stable/build_meta.html#dynamic-build-dependencies-and-other-build-meta-tweaks does not work in some cases due to setuptools invoking setup.py during get_requires_for_build_wheel.
If this gets removed, what's the recommended alternative?

@jaraco is this direction something that makes sense to investigate? |

Summary of changes
This started as an exercise in #4973 (comment)
The idea is to avoid all the patching involved in making
setuptools.build_metacompatible withsetup.py.Currently
no_install_setup_requiresis patching the distribution class that is already patched bysetuptools.monkey. It looks very fragile.(Granted, this PR replaces patching with magic argv flags + a bunch of
if-statements, but that can be slightly better?)Closes
