[riscv-CMOs:master] New Comment on Issue #45 Interaction between management instructions and dirty bit
So, whilst in practice there may not be a security justification for mandating PTEs be writeable, I strongly believe that that relaxation makes it a complete nightmare to have any kind of sane behaviour when it comes to accessed and dirty bits, and that the extension should just follow other architectures like AArch64 and require write permission rather than trying to be clever about it.
