I'm not enitrely sure what you are asking.  Are you asking if that's the
only way?  Not sure, but I think that's the standard way to do such
stuff.

Or are you asking if that will make that work for all standard AUCTeX
completion functions.  I guess so, although just setting

  (setq-local completion-extra-properties
              '(:annotation-function
                (lambda (x) (message "AF: %S" x) "foo")))

or let-binding it around the `completing-read' call in
`TeX-insert-macro' had no effect.  The function has never been called.

Only that it hasn't been updated within the last 2 years doesn't make it
outdated.  It just means nobody felt the need to add even more symbols,
maybe because it is already comprehensive enough.
