I should be more explicit in that you'd remove Nginx here, too, but
instead add in a uwsgi server (which is a great piece of software but
has a higher learning curve in itself than anything you've tried here
so far, I fear).

And in this variant you'd remove Apache httpd completely.
But the Shibboleth integration with Nginx is difficult and possibly
not well implemented.
(And likely you'll be proxying from Nginx to another web server via
HTTP anyway here, too? So you'd probably still be HTTP proxying and
couldn't make use of environment variables.)

Just to be a bit more clear on the implications.
