I don't think /usr/bin/python should ever point to a python3 version.  It should be dropped when python2.7 is removed.  I think the existence of /usr/bin/python2 is a limited to a work around for a specific distros insanity.  There's no need to encourage it's use in Debian as that particular insanity hasn't and won't (as long as I'm a python*-defaults co-maintainer).
