I dunno, it literally has “hack” in its name. If we can’t do before-hook, maybe its best to let major mode setup normally and locally bind treesit-enable-function, which treesit-mode calls should user add it to major mode hook.
And if a user wants more control (eg, use tree-sitter for indent only), he/she assigns the tree-sitter function to indent-line-function, etc. No hand-holding from us.
Buuut, if a user wants tree-sitter for parent mode but not derived mode, they need to write
(add-hook 'xxx-mode-hook
(lambda () (when (eq major-mode 'xxx-mode)
(treesit-mode))))
Which again is a bit awkward.
So maybe a central variable isn’t that bad an idea. Could you layout why mapping modes to some information is bad? Can we fix it somehow?
