MPU isn't used very often in Rust projects, but it still has value to protect against:

* code or hardware bugs, particularly things like DMA overwriting wrong data, or some kind of `unsafe` issue, Undefined Behavior, or miscompilations
* If you have separate "userspace" and "kernel" code you want to isolate
* MPU can help with things like stack overflow, that can't be detected by the compiler
