In terms of distribution format, this sounds great; I think a clean
break and new format that existing systems will just naturally ignore is
the way to go.
Your message doesn't address the on-disk installed format. I hope that
the installed format (at least the d2/p default) will be consistent with
PEP 376 (unzipped and "flat"), not an egg-style importable zip file
relying on its own dedicated entry in a pth file.
