Alternatively, you could just approach the concepts of inter/intra-task/driver/kernel protection from a new perspective, and do something like The Mill Architecture: https://millcomputing.com/docs/#security

I would argue that an OS meant to run on a smallish battery has particular tradeoffs.
You can't ignore computing overhead like you can on a big laptop or desktop. Keeping it leaner is more justifiable.
And for what it's worth, my iPhone has never brought down the OS from a bad webpage. It has always been the browser crashing and restarting *the browser*. This is an amazing stability record. The CSS bug is the only bug of its type I have heard about.

Whenever there's a problem, you fanbois evoke the SJRDF, and spin it has a the exception that proves the INSANELY GREAT nature of Apple products.
Come on, man. Just say it: This is a terrible bug; Apple screwed up, and will hopefully do better in the future.

It is a critical bug that must be fixed immediately.
That does nothing to negate the very stable experience I have had with my iPhone.

TI RTOS Kernel has no concept of memory mapping. Everything runs in physical memory
This is very common: MMUs are expensive, take up lots of silicon real estate, consume power, produce heat and use lots of memory
Yes it takes memory to map memory. It's not uncommon for memory protected kernels to have a gig of page tables. That's why the Linux kernel mailing list is so full of discussions about reducing memory fragmentation: two discontinuous memory mappings will consume two page table entries
I do embedded and drivers because my clients are happy to give me all the time and money I require to get all the bugs out. My GUI client's were never that way
