There's no need to get snarky. I've used similar parts before, for example TI's Hercules RM4 does not have an MMU either and so what I said wouldn't apply there. But that doesn't mean you would never have an MMU.
Indeed, my apologies. I actually quite like the idea. It reminds me a lot of Erlang, where you set up a bunch of small processes and if any of them die, you can a) try to recover quickly, or b) run in reduced functionality mode. I just haven't been fortunate enough to work with embedded processors where it'd be a good fit; they've either been on the small side (Cortex M, MSP430, AVR) or on the big side (iMX6, AM335x) and just run full-blown Linux.
