Cool! Some comments:

+(defcustom c-ts-mode-font-lock-feature-list
+  '((comment preprocessor operator constant string literal keyword)
+    (type definition expression statement)
+    ())
+  "Language constructs to font-lock.
+
+See `treesit-font-lock-feature-list' for description of how to
+use this variable.  Supported features are as defined in
+`c-ts-mode--font-lock-settings'."
+  :version "29.1"
+  :type 'list
+  :safe 'listp
+  :group 'c)
+

I think Stefan M’s opinion is to make feature-list private, and let users add/remove features. Right now they can add/remove features with treesit-recompute-feature-list. I guess we can keep them as defvar’s for now, so people as the option to redefine this list should they want to. (One argument against having them as custom options is that, if a user sets it as a custom option, they will miss out on future changes to this variable.)

+  (setq-local comment-style c-ts-mode-comment-style)

Why don’t we let users set comment style themselves? Does cc-mode have a similar variable?
