This is true on the iOS platforms I'd say but it's not on the macOS ones: There you can just run your own code shortly after the SoC boots and then just leave SPRR/GXF disabled. That way you can easily have all rwx pages all you want.

you can also just map the same physical memory once as rw- and once as r-x even with SPRR enabled there.
