Interesting, there is more life in Congestion Control than I might have
thought.  But it begs the question, is this something that the IETF
should be involved with or is it better handled by those who are
developping LTE etc?

From the little I know about TCP proxies, they are horrible beasts
that can impact application layer semantics. Figuring out how to deal
with mixed e2e paths (partly lossy, partly congested) seems to me
very much an IRTF/IETF topic, even if we don't have an AD who is
a subject matter expert.

There is a huge cross layer optimization issue between 3gpp and the ietf. It is 
worse than you can imagine, highly akin to how the industry moved passed the 
ietf with Nat. The same thing is happening with tcp.  Tcp is simply not fit for 
these high latency high jitter low loss networks.

Google is a player in the e2e space for various business reasons and it appears 
they are now in an arms race with these horrible mobile carrier proxies (which 
in many cases do on the fly transcoding of video).

There are 2 fronts. 1 is quic as linked above. Another is their own transcoding

This is not novel. Opera mini has been doing this for years, otherwise know as 
opera turbo. Oh, and Nokia has been doing it too.  They even help by bypassing 
pki and any sense of internet security.

Hold on to your hats.
