Our preference is to have secretmem available to everybody. As James nicely put it [1]: I don't think dividing the world into people who can and can't use secret memory would be useful since the design is to be usable for anyone who might have a secret to keep; it would become like the kvm group permissions: something which is theoretically an access control but which in practise is given to everyone on the system.
