Doc change b264d5bfb8 did remove
whole mod_proxy_uwsgi section based on not possible under PY3,
PY27 was still supported in Train and while broken the
started and served subset of requests just like with pure
uWSGI deployment. This patch returns that section with
clarified warning.
This is only relevant for Train and before.
