Maybe I missed something (I'm having trouble keeping up with
emacs-devel these days, sorry), but I don't see why you think so.
It seems perfectly appropriate (and indeed fits the original goal) for
`Commentary:` to say something like:

    ;; If you want to use this mode by default, you can add the following
    to your init file:
    ;;
    ;;     (add-to-list 'major-mode-remap-alist '(ruby-mode . ruby-ts-mode))
