Can we gather data? What if pip started reporting info on how it was
run when contacting pypi?
What info would be useful? I guess whether it's pip/pip3/python -m
pip/python3 -m pip would be nice to know. I don't know if
sys.executable would tell us anything useful or not. pip knows where
the current python's script directory is; maybe it should report
whether it contains 'python2', 'python3', 'python', and perhaps which
ones are the same as each other?
