"app server + proxy + startup model" still in development?

Continuing the discussion from VirtualMin Manual Django Installation:
@Joe wrote: Jamie was working on adding easier setup for this sort of “app server + proxy + startup” model, but I’m not sure if it’s in 6.16 or still in development. But, you can already setup proxy rules in Virtualmin, if you don’t want to do it on the command line.

Is there any news on this?

PS: I’ve deleted my virtualmin servers and, following the directions at “How to install and use NGINX in a Virtualmin hosted environment”, I’ve re-created them under NGINX.

The further directions at “Deploy Flask The Easy Way With Gunicorn and Nginx!” seem like the way to go for my case: Having developed an app under Flask/ngrok (unfortunately, under Anaconda, as I didn’t realize how heavily the WSGI world is dependent on pipenv as opposed to Anaconda for version alignments), I needed to escape the http-service of Flask used in development while retaining the Flask app for deployment.

PPS: Looking around for related documentation, I ran into a 404 with the ruby on rails link:

https://www.virtualmin.com/documentation/webdev/rails

Those instructions are years out of date.

The way to install Virtualmin with nginx is: /bin/sh install.sh --bundle LEMP as documented.
