There seems to be something missing in the new text:

  +@defun treesit-defun-at-point
  +This function returns the defun node at point, or @code{nil} if none
  +is found.  It respects @code{treesit-defun-tactic}: it returns the
  +top-level defun if the value is @code{top-level}, and returns the
  +immediate enclosing defun if the value is @code{nested}.

This mentions treesit-defun-tactic, but that variable is not
documented anywhere in the manual, and is not indexed.  It should
either be documented in this node, or in some other node with a
cross-reference from here to that other node.

In general, please remember to index every function, macro, face, and
variable unless they are in @defun/@defvar/@defmac etc., which add
index entries automatically.
