This doesn't seem like it would be attractive to distributors to me.
For them, it's just as easy either way to drop a file into
/usr/lib/python3.5/ versus /usr/lib/python3.5/site-packages. But if
you use site-packages/, you have to make sure you also have a patched
virtualenv and pyvenv, and worry about whether your distribution will
ever get used with old versions of virtualenv, etc., whereas if you
drop it into the stdlib directory then it just works robustly
everywhere. I guess we could put some finger-wagging in a PEP telling
them to use site-packages/, patch virtualenv, and eat their
vegetables, but I don't know why they'd listen to us :-).
