I didn't actually write this up per se :P Technically, I dictated it and there's probably some gnarly typos with homophones in there that I haven't totally eliminated because it was a bit of a fire and forget piece, where I was just dumping my thoughts on a topic.
And yeah, even notwithstanding the massive accessibility benefit, I can see use in learning it just for the sake of a new lens on how to navigate code. Sort of the same reason I'm looking forward to the big Emacs 29 update on all my machines around the end of the year - among other things, I get to find out firsthand whether I'm as excited as I should be for first class tree-sitter, or not excited enough.
But for VS Code folks, this is already right there and I can't imagine not wanting to play around at least a bit with it and see what it can do.
