Good.

Ok. Anyway, the Python external modules are installed
in /usr/lib/python<version>/, so micropython will not see them. So
we're safe if someone enables both micropython, python 2 and a bunch of
python external modules: python 2 will allow to use the python external
modules, and micropython will live its own life without providing
access to the python external modules.

Sure, makes sense.

Isn't it a bit problematic for an open-source project to not have a
clear license (or list of licenses) ? It basically means that you can't
safely redistribute it.
I believe listing all the licenses is the proper course of action here.
Something like:
<foo>_LICENSE = MIT (this, that), BSD-2c (foo, bar)
Thanks!
