Yeah I know it is possible, just not trivial. So for me it was more complex to implement it in the browser than just create a simpler tree-sitter.

LSP and tree-sitter solve different problems and aren't interchangeable, it sounds like you were trying to pound a square peg into a round hole.

LSP doesn't (nor can it) specify anything that would make your life easier to use a language server in the browser. There are editors that provide clients and language servers written in JS, though.
