Hmm, OK. At the moment that stuff (except pip show) is all covered by the running of the egg_info command, I guess. So you're saying that pip should first check if a requirement has new-style metadata and if it does, skip the egg_info command and use pydist.json. I guess that would be good - it'd solve the problems we see with numpy-related packages that need things installed just to run setup.py egg_info. It wasn't something I'd particularly considered, but thanks for the clarification.
