That makes sense to me.

I'm not a big fan of the docstrings generated by this, is there a way to
change them to be more helpful? For example, syntax-state-comment looks
like this:

syntax-state-comment is a Lisp function.

(syntax-state-comment CL-X)

This function has a compiler macro ‘syntax-state-comment--cmacro’.

Access slot "comment" of ‘(syntax-state (:constructor nil) (:type list))’ 
struct CL-X.

But it would be a lot better (in my eyes, anyway) if it looked something
like this, had the -p suffix, and made CL-X default to point:

syntax-state-comment-p is a Lisp function.

(syntax-state-comment-p &optional CL-X)

This function has a compiler macro ‘syntax-state-comment-p--cmacro’.

Return non-nil if the syntax of CL-X is a comment. CL-X defaults to point.
