I use it for lilypond for notation. I always considered it superior to Finale and Sibelius anyway. Not sure how it stacks up against the more modern commercial notation apps. But I love having a real trackable version history of my pieces.

What's also cool is the more advanced llms know lilypond and music theory too, so they can do things like... I don't know, check for counterpoint errors. I've used it with limited success to expand my jazz lead sheets into two-hand piano arrangements just for practice exercises.

there are plenty of text-based digital music notation systems. Then, you commit periodically as your composition evolves, and you can have all the history/fork/undo whatever that you might want.
