Are there any commercial mappers that implement any sort of privilege levels/rings or anything akin to memory segmentation/protection in PRG-RAM? Granted you couldn't protect the entire address space, but theoretically I imagine it'd be possible with mapper hardware to exercise some level of control over access rights to sections of PRG-RAM or something like it. Not that there's much need for the security aspects, but protecting some memory against errant interaction by stepping between privilege levels and handling privilege violations in a standard way could offer some stability benefits I imagine.
