This is IMO an important question.

We agree, I believe, that forbidding middleboxes that do some transport 
relaying is unrealistic.
(In other words, for the real world Internet,.the EME model must be 
accepted in addition to the E2E one.)

Then, there seems to be no simpler place, to recover from transport 
relay failures, than just above the transport layer..
It is thus not a surprise that  real applications, that had to adapt to 
the real transport world with no extra layer between transport and 
themselves, already have that recovery mechanism.

 It would indeed be a first _as an recognized model_, but AFAIK not in 
implemented code.
