Ah.
You are speaking about having a factory to create enclaves and a
management interface. I.e. you'd have ioctl to create enclave that gives
you a file descriptor to access its management interface.
Out of top of my head I cannot recall why this was not favored in the
end but generally speaking added complexity should be justified by some
considerably strong measures.
