It's nice to see SMM is as terrible idea now as it was at moment of conception.

All coz they can't be arsed to put a tiny management core separate from the rest and save a penny

ARM has EL3, which is basically the same thing. There's nothing inherently wrong with the CPU having multiple privilege levels. The problem with SMM has always been its user-hostile opaque implementation, not that the technical mechanism exists.
