This is probably extensible to any data storage-and-retrieval feature where there is A. no pre-processing, and B. no more post-processing than can be realistically done at render time. That still expands the universe of possible features a good bit.

Yes, showers are indeed often very illuminating!

The fact is that inside of the web application what you are doing is only REST requests to a backend system
that means that the content of the response cannot manipulate the DOM of the page therefore you are not
worried of sanitizing data.

I illustrate this approach in a post I did how we could in future do crypto safely inside of browsers:

manipulation).
