OK, so we're going in circles now.

I don't believe we necessarily *WANT* or need Linux to support "all
possible ECREATE, EADD, EEXTEND, EINIT sequences".  Yet, it's what is
being used to justify this series without any other justification.

It's going to be a different story if you bring me a real enclave that
*REALLY* wants to do this for good reasons.
