I agree, TikZ options are indeed too heavy for AUCTeX.

Give digestif[1] a roll; installation is really straight forward.  And if
you have eglot, starting it should work OOTB.

Not that I'm aware of.  With the current implementation:

(defun LaTeX--env-parse-args (args)
  "Helper function to insert arguments defined by ARGS."
  (save-excursion
    (LaTeX-find-matching-begin)
    (end-of-line)
    (let ((TeX-exit-mark (or TeX-exit-mark
                             (make-marker))))
      (TeX-parse-arguments args))))

You can set `TeX-exit-mark' inside args which is parsed by
`TeX-parse-arguments', but it doesn't work since the code for moving to
that point is only available in `TeX-parse-macro' and not in
`LaTeX--env-parse-args'.  Further, `save-excursion' would nullify a
point movement anyway.

Hence my suggestion which respects `TeX-exit-mark'; either set by a
function in `args' or the value returned by `point-marker'.

(defun LaTeX--env-parse-args (args)
  "Helper function to insert arguments defined by ARGS."
  (let ((TeX-exit-mark (or TeX-exit-mark
                           (point-marker))))
    (TeX-parse-arguments args)
    (goto-char (marker-position TeX-exit-mark))
    (set-marker TeX-exit-mark nil)))

Where do you expect a potential breakage?  Maybe I'm missing something?

Best, Arash
