Hey sorry, I was busy with some other things. I’ve looked at the patch,
it seems adding a hook that sets treesit-simple-indent-rules would have
the same effect, no? (Ie, user already can set a custom indent style)
Like instead of

(defvar my-personal-csharp-mode-indent-rules (...))

(setq csharp-ts-mode-indent-style
      (lambda () my-personal-csharp-mode-indent-rules))

you can just do

(defvar my-personal-csharp-mode-indent-rules (...))

(add-hook 'csharp-mode-hook
          (lambda ()
           (setq treesit-simple-indent-rules
                 my-personal-csharp-mode-indent-rules)))

This way there is no need to define a custom option and a function for
each mode. And users can use the same variable
treesit-simple-indent-rules, just in different major mode hooks.
