I can kinda see the reason for this being valuable on it's own, but in
general why does TDX need a gazillion flags to disable tons of different
things if _ALL_ these flags are going to be set by for TDX guests
anyway?
Seperate flags make only sense when they have a value on their own,
i.e. are useful for things outside of TDX. If not they are just useless
ballast.
