Hello,

while python-requires is indeed nice, it is only usable by pip to select a
wheel file with a fully compliant PEP 503 repository.
Otherwise, like in a local wheelhouse (wheel files in a directory), it is
invisible to pip until pip tries to install the wheel so a more precise
python tag can still be somewhat useful...
(I agree that pip could access the wheel metadata to check the
python-requires without needing to unzip the whole file).
