As mentioned above, the answer is no. I am not willing to turn off a hardening feature for the entire architcture to support ancient CPUs. The Technical Committee might give advice to do it anyway. >Hardware that support it for sure would still be protected that way No, there is i386 hardware that can run current sudo just fine. As far as I know, only a certain CPU family that has some market share in the thin client market is affected by this. Current sudo is perfectly usable on most i386 CPUs.
