Could you share a little more background here? Hardening is good, but you _can_ have too much of a good thing.
Is this part of the boot cycle becoming a target for attackers in trusted boot environments? Do emerging confidential computing technologies like SEV and TDX cause increased reliance on compressed kernel security?
In other words, why is *THIS* important versus all the other patches floating around out there?
