Okay, I've been convinced that keeping the dynamic path feature is a good idea. I am really looking forward to seeing the rationale added to the PEP -- that's pretty much the last thing on my list that made me hesitate. I'll leave the details of exactly how the parent path is referenced up to the implementation team (several good points were made), as long as the restriction that sys.path must be modified in place is lifted.
I've updated the PEP. Let me know how it looks.
I have not updated the implementation yet. I'm not exactly sure how I'm going to convert from a path list of unknown origin to ('sys', 'path') or ('foo', '__path__'). I'll look at it later tonight to see if it's possible. I'm hoping it doesn't require major surgery to importlib._bootstrap.
I still owe PEP updates for finder/loader examples and nested namespace package examples. But I think that's all that's needed.
