RE[7]: MicroKernel's

You can have memory protection even if you run in supervisor mode. Only supervisor code is "capable" of changing the MMU/MPU to enhance its rights.
But if the supervisor code is proven (big word I know) to be correct (either mathematically or by design/review: Check IEC61508), then there is no problem.

But for sure, the more software is in userland the easier to protect the kernel and other parts of the system.
