Is it at all possible to create a solution that works well for all cases?

I pitched a proposal at IETF75 and then again a year ago in TCP/TCPM WGs 
that it might be good if the connection manager could hint the TCP stack, 
or the TCP stack could determine itself by heuristics, that its network 
connection were of a few different degrees of a few criteria which might 
be speed, loss, jitter etc. I perhaps even could tell my connection 
manager that when connected to my home wired or wifi network, "everything" 
is reachable via 50 + megabit/s connectivity. If I then speak to a 10GE 
connected server, there should be no problem for it to do IW10. Basically, 
my thinking is to have something similar to "MSS" but when it comes to 
connectivity.

There was no interest anywhere in this, everybody wanted for each 
connection to be living in its own universe with little prior knowledge 
about what's been going on before it.

I just don't see how we can make things work well when we try to create 
TCP to handle everything from 1500ms to 0.1ms of RTT, and everything from 
19200bps to 100GE in speed.
