That happened because I got a bit lost in the way finders were working in setuptools, which seemed a bit over-engineered at that time to me (but I might end up changing my mind at sime point when I understand it better).
The finders mechanism is there to allow support for arbitrary PEP 302 importers -- i.e., sys.path strings that don't go to the filesystem.
The main reason why there are two finders currently (find_on_path and find_in_zip) is that find_in_zip supports egg directory bundling. That is, an .egg zipfile may contain arbitrarily nested .egg directories, and an .egg directory may contain arbitrarily nested .egg directories or .egg zipfiles.
However, if you're not implementing dependency resolution, you don't need that support. If such a nested item were in use, it'd be on sys.path already. (In other words, the nesting lookups are only useful for alternate version discovery, not simple metadata lookups.)
