Of course, now we have SMM, perhaps we should revisit the model where
the SeaBIOS CSM just takes over the hardware completely (and cannot
return to UEFI).

I understand that the "traditional" model is that the CSM does
basically nothing for itself, and all its drivers (like the INT 13h
services) actually just thunk through SMM to the UEFI runtime?
