I am wondering how the third-party parsers are going to scale for larger
Org files. I did some simple testing in the past, and it seems that only
tree-sitter can potentially get sufficiently close to org-element in
terms of performance. Maybe we should implement a Elisp LSP server
instead of many individual parsers in different languages?
