This reminds me...

One really nice thing about having a flat namespace for modules is that if
you start writing a module directly into your current project, and then
later realize it (and some others) should be split out into a separate, more
generic, library or application, none of the calling sites elsewhere have
to change and you don't have a minefield of "from foo.bar import biz.baz"
locations to update (or pray that a tool or script fixes correctly).
