The UEFI specification still opens with a promise to preserve the existing ecosystem: evolutionary rather than revolutionary, built on existing investment. That consensus holds, and nobody wants to break the installed base. But the requirements arriving now from cloud providers, hyperscalers, and operators of sovereign infrastructure ask for what it was never designed to deliver: compute whose trustworthiness is owner-controlled, verifiable from the root of trust to the handoff to the operating system, and reproducible by more than one party. Trustworthy by evidence, not by assertion.
