Node-RED as a platform for complex web applications?

It was actually one of the first things I created with Node-RED: it was called RedBack - Node-Red as Backend and lead to one of my favourite comments here at the forum:

So it has the potential to get misundertstood when using a web application to create another web application, even if you think it's amazing to create a visual web application with Node-RED.

EDIT:

I continued on and my blog on Node-RED is running NR with the content actually being the flows, i.e., articles are flows, there is no database backend to store content.
