"auctex-label-numbers" or "auctex-cont-latexmk" come to my mind.

I'd like to see the functionality of

• tex-item.el
• tex-parens.el and
• tex-numbers.el

in AUCTeX.  But I'd suggest you make all your packages available via
ELPA now in order to get some feedback.  You can
remove/obsolete/whatever them once the code is merged.  I think it will
take some time to review/polish the code, e.g.:

--8<---------------cut here---------------start------------->8---
(defun tex-parens--beginning-of-defun ()
  "Move to the beginning of the current defun.
Here `defun' means top-level environment."
  (interactive)
  (re-search-backward "^\\\\begin{[^}]+}" nil t))
--8<---------------cut here---------------end--------------->8---

Why do you use an internal name for a command, or:

--8<---------------cut here---------------start------------->8---
(defun tex-numbers-update-cache (aux-file)
  "Update the cache for AUX-FILE.
Return the updated cache, or nil if the aux file does not exist."
  (when (file-exists-p aux-file)
    (with-temp-buffer
      (insert-file-contents aux-file)
      (let ((cache (make-hash-table :test 'equal))
            (pattern "\\newlabel{\\([^}]+\\)}{{\\([^}]+\\)}"))
        (save-excursion
          (goto-char (point-min))
          (while (re-search-forward pattern nil t)
            (let ((label (match-string 1))
                  (number (match-string 2)))
              (puthash label number cache))))
        (puthash 'timestamp (current-time) cache)
        (puthash aux-file cache tex-numbers-cache)
        cache))))
--8<---------------cut here---------------end--------------->8---

I think pattern should be "\\\\newlabel{\\([^}]+\\)}{{\\([^}]+\\)}"
if you want to pass it to `re-search-forward'.

But I suggest we move the discussion about "which part to upstream" to
auctex-devel.

I think you qualify to start hacking on AUCTeX and push it in any
direction you (and other users) think it should go :-)

My pleasure.
