That's a very kind way to phrase things :-)

For initial upstreaming, we've agreed that there is no need to extend the
uapi, i.e. we can punt on deciding between on-the-fly tracking and having
userspace specify maximal permissions until we add SGX2 support.

The last open (knock on wood) for initial upstreaming is whether SELinux
would prefer to have new enclave specific permissions or reuse the
existing PROCESS__EXECMEM, FILE__EXECUTE and FILE__EXECMOD permissions.
My understanding is that enclave specific permissions are preferred.
