If for some reason menu-updating-frame is not set when it should (due to
a bug or a overlooked case) then it is much better to enable menu items
than to disable them by default.  When a menu item is enabled with its
updating frame invisible, it is not a disaster.  But when menu items are
permanently disabled (for another overlooked case like non-toolkit builds),
this makes menus in Emacs unusable.  The change in menu-bar.el makes such
an unfortunate situation impossible.
