I like the promise of explicit notification of congestion, and
have enabled ECN on my computer. However, I am always forgetting
it is on and getting paranoid before I remember it and turn it
off in order to communicate with a server behind a non-ECN firewall.

How difficult would it be, I wonder, to set the TCP stack to
attempt a non-ECN connection if the first SYN does not come back
in reasonable time? That is, send the second (or third) initial
SYN without the ECN option?

In effect it would be a third ECN mode besides on and off: Auto.

And it would make a good default.
