I don't think we should do much effort to support Python 2, but it comes
almost for free: only shebang needs to be different, and, if the comments
inside the doc contains non-utf8 chars, an encoding line.

The current tools during Kernel build currently supports it (again,
except for shebang).

Anyway, from my side I'm happy either way.

Fine from my side ;-) There are some precedents here, so I guess it
should be up to each subsystem to decide using it or not.
