It could be best. Any code that depends on a major mode will likely
break in multi-mode environment if it's not aware of it.

Maybe have a secondary local variable that would point to the current
submode (like mmm-current-mode).

I'd rather not do that. Some modes override common commands via the
keymap, rather than some `-function[s]' hook.

What about submode-local minor modes and their keymaps? Do we prohibit
those?
