I do favor transmitting the full 64-bit ESN in packet. And I can add this
solution in the next version.
In fact, this is one candidate solution I considered at the beginning. But I
thought modifying the ESP packet format was a very significant change. I was
afraid that people would think a new ESP version is required and not accept it
by only using this notification. So I was not brave enough to write it in the
draft v00.
