Before I look at the patch in any detail: That's only the Technical Paper,
not the specification. Are you sure you also mean to remove that capability
from the spec? I.e. not allowing re-consideration in the future, or others
to implement only a 256-bit variant? Even if so, should we really rip out
everything, rather than just making that feature default-disabled?
