One more thought: the new menu system would give us the chance to redesign the menu display strategy, similar to what current browsers seem to do, maybe related to necessary Wayland changes since Wayland has limited user control about popup (menu) windows.
It looks like recent Firefox opens one "main" menu window and displays submenus by "shifting" the main menu out of the menu window, making room for the submenu - rather than opening a second (and third and fourth ...) window. Example: click the "hamburger menu", then on "Help" or "More tools". This is true even for the X11 version of Firefox [1].
I'm not sure if this is the *best* way to deal with (user) menus but there's at least a chance for a menu redesign that is more Wayland compatible than our current menu system. Particularly very long menus are problematic and could be improved by a new menu system.
[1] FYI: You can start a new instance of firefox as a Wayland process if you set an environment variable and use another profile than already running firefox processes, for instance: 

$ MOZ_ENABLE_WAYLAND=1 firefox -P
Commandline switch -P runs the firefox profile manager so you can either use an existing profile or create a new one if necessary.
