Note this would make M-mode X-only PMPs effectively useless (except on M-only implementations, where the MXR bit does not exist).

My thought earlier was that MXR would be honored only when MPRV was in effect (ideally, R-only pages would fault when accessed under MXR+MPRV)

That makes it less likely for software to make MXR-related bugs, but doesn't close the M-mode X-only hole (as you can set MPRV=1, MXR=1, MPP=M).

Plan is to leave it as defined (only affects paging, not PMPs), and see what happens.
