If most of your modules are pure-Python or maybe a little bit of C, then you might not be running into the warts that the current packaging systems have.
Also, running 'pip install package' hides what kind of lengths that developers/package maintainers have to go through to get things working correctly. That's also part of the discussion when talking about a decent packaging system.
