Using RISC-V ISA, BOOM open source OoO core, and Berkeley's "FireSim" FPGA simulation environment.
Just recently we had quite a few reports from those efforts.
You can look for vulnerabilities in those production system, sure, and try to find work-arounds, but that's kind of short term tactics not fundamental research.
That is how stuff like SPARC ADI, MTE, PAC, Azure Sphere, CHERI, Morello, comes into existence.
For which I don't criticise him at all -- it's a very sensible decision.
