This.. This is exactly what I was thinking. Well put. The complexity it would add the Linux kernel code base would probably, inadvertently, create more security issues. The more code, the larger the attack scope. In general, as a security researcher, I would tell people to let hardware do most of the lifting when possible as software being involved usually means introducing a higher probability of bugs/vulnerabilities.
