This is still something consumers need; at the moment users have no
idea if data is *actually* being encrypted. I think Martin has done an
admirable job going down the rabbit hole to add this functionality in
the proper manner -- so it's actually accurate and useful for other
use cases to that of fwupd.

At the moment my professional advice to people asking about Intel
memory encryption is to assume there is none, as there's no way of
verifying that it's actually enabled and working. This is certainly a
shame for something so promising, touted as an enterprise security
feature.
