On the carpal tunnel claims, I'd expect the author to be using a setup that is ergonomically massively more comfortable for typing than anything else. Basically the opposite of PC gamers who won't settle for meh ergonomics on their interfaces.

This seems to be a tad faster and easier to use that PlantUML/Mermaid/WedDiagrams when representing simple flows, or at least straightforward diagrams.

The main trade-offs I personally see:

- I actually want control over the layout. The goal of the diagrams is to convey info in a readable way, and getting a spaghetti when it becomes too complex doesn't help.

- Straight text base solutions allow for pattern replacements, snippets, whole copy/past from different docs etc.

- Aliases don't seem to be supported. Typing over and over the node names isn't fun.
