As I said in the meeting, I have an alternative proposed design:

- Packet has type P
- Encrypt the packet and call the last byte of the packet (the auth tag) T
- Set the new packet type to be P ^ (T & 0x7f)

This randomizes the packet type without placing any special requirements on the construction of the code points.
