This seems ill advised. He should really justify why he is doing this, and why, in particular, it makes sense for mod_python to gain python3 support.

I don't know of any currently-developed framework that hasn't deprecated mod_python, and for good reason. wsgi and uwsgi are superior solutions in every way. I don't want my python code running within the Apache process.

I am in the process of migrating all of my development to uWSGI. This also has the advantage of entirely de-coupling from Apache, so that I may move a given app to nginx at will.
