Comment (by westonruter):

 This is a good one. If a theme doesn't have styling to support tertiary-
 level submenus, then they shouldn't be allowed. Basically I think this
 will need to be a param added `register_nav_menu()`, and when a menu is
 assigned to that location it will need to prevent nesting deeper than the
 location to which the menu is assigned. It gets tricky however in the case
 where the same menu may be assigned to multiple nav menus which may have
 conflicting depths mandated.
