Lars, would you please tell us why? He already did, see https://lists.gnu.org/archive/html/emacs-devel/2021-10/msg02399.html https://lists.gnu.org/archive/html/emacs-devel/2021-10/msg02402.html Bottom line: they were deemed unnecessary, since the key bindings that use the prefix also show the prefix. We could add a user option to get that back, if we think people will want that sometimes.
