Here I have for example the following tri-state -mode variable:


scroll-bar-mode is a variable defined in ‘scroll-bar.el’.
Its value is ‘right’

Documentation:
Specify whether to have vertical scroll bars, and on which side.
Possible values are nil (no scroll bars), ‘left’ (scroll bars on left)
and ‘right’ (scroll bars on right).


So I see no problem in making 'menu-bar-scrollbar-mode' a multistate
variable.  Maybe one day someone wants to add a ">>" in the top right
corner to reveal further menu entries.
