Verified boot on Qubes -- a lofty dream?

This thread is somewhat entertaining and I’d like for it to go on (it also helps increase visibility of the post, which is nice), but it’s definitely not about verified boot on Qubes anymore.

Can existing threads be split? If so, may I request that a mod split the thread at one of the earlier points where the conversation became dominated by discussions about Purism?

P.S. According to Liam Gray in a relevant thread, Trammel Hudson is working on AEM for TPM 2.0
