OK, thanks for the summary.

Personally, I still think the biggest issue is around pyc files. I
think any proposal needs an answer to that (even if it's just that
no-optimisation mode never reads or writes bytecode files). Expecting
users to manually manage pyc files is a bad idea. Well, that and any
implementation complexity, which I'll leave to others to consider.
