I’m in process of moving so I’m a bit scattered brained at the moment and I don’t have the time to look into the specifics but if this is for the build interface (vs the shim) then I don’t think we should support plain ``install``. Opting into the new format should mandate the capability of producing a wheel and then installing from that instead of being able to directly install.

If we consider the setuptools/distutils era to be “Make it Work”, then we’re now at “Make it Right”, making it fast can come later but sacrificing correctness for speed isn’t something I think we should be doing and so speed arguments (vs why it’s more correct to do X instead of Y) don’t matter much to me.
