I'm left with the following questions:

- if you want a new UDP protocol number, why not just us 33 (DCCP)?

- if NATs would not be an issue to a new transport, why has it inhibited
all the recent attempts? (DCCP, SCTP)

Although I appreciate the implications on TAPS for "do what I mean"
negotiation of alternate transports, TAPS doesn't solve either of the
issues above.

AFAICT, they both highlight:

a) why this is hard

b) why this doesn't actually need a new IANA transport protocol codepoint
