Do I understand correctly that `treesit_record_change' is called __less frequently__ compared to before-change-functions and after-change-functions? If yes, I do not see how exposing it to Elisp will make things any worse than already available `before-change-functions'/`after-change-functions'. Elisp code that does not care about text property changes will not be forced to use `before/after-change-functions' (because no other option) and could be called less frequently. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
