one of the most interesting things about this work is that it might be the gateway drug that finally leads to widespread deployment of real memory safety for C and C++

I have a more pessimistic outlook: these kinds of mitigations will just prolong C and C++ lifespan, while being quickly defeated by exploit authors, worsening security overall

In my opinion, features like this work far better with memory safe languages where memory corruption bugs are very scarce. The attacker doesn't have the opportunity to choose from a huge selection of bugs / helpful memory corruption primitives to build a reliable way around it.
