There's no such writeup.
But look - most people don't actually want to connect multiple applications together to make music. Most people don't actually want to move audio between applications at all. As we get more and more (reasonably) good plugins available on Linux, the "monolithic" approach - do it all inside one program (e.g. a DAW or something a bit like it) is easier for most people (no complex state management) and closer to their pre-existing mental models.
If you do need/want to connect multiple applications together, then sure, JACK is great and better than more or less any other possible alternative for that purpose.
But most people don't want to do that, and increasingly do not need to either.
