discussion, not issue: minimum macOS version in setup.py, so pip checks wheel macOS / user's macOS

[denis-bz]

Please move this to "discussions":

Is your feature request related to a problem? Please describe.
Pip happily installs a wheel built on macOS 10.15, which crashes on my 10.14 --
see python-pillow/Pillow#3068 (at the end).

Describe the solution you'd like

1. a minimum macOS version in setup.py / in wheel metadata
2. could pigar then check that ?
3. pip should use it, so not install e.g. wheels with minimum macOS version == 10.15 on older macs.

Describe alternatives you've considered
None -- sounds unlikely

Thanks, cheers
