I don't think pip actually has any use for the PEP 517
prepare_wheel_metadata hook right now though? Historically 'setup.py
egg-info' was needed to kluge around unwanted behavior in 'setup.py
install', but with a PEP 517 backend that's irrelevant because
'setup.py install' is never used. And in the future when pip has a
real resolver, then prepare_wheel_metadata should allow some
optimizations. But right now, prepare_wheel_metadata is completely
useless AFAIK.

So why is 'setup.py dist_info' a blocker for things?
