Have you read my proposal? It's in the message posted by me to this thread at 12:31 PM today. My main motivation in proposing it is to give the user complete control over the Python environment that is in their path -- which is not easy to do on Debian/Ubuntu at the moment -- by giving the Python utilities and packages that OS-related functions depend on a completely insular Python environment that the OS can manage however it sees fit. In my view, both as a developer and a user, but especially as a developer, it would make life easier.
