First, you are ignoring a TCP_RST, which means "stop trying".

You would have to retry a connection with a new source port. How do you handle
cases where the application explicitly bound the socket to a specific source
port / source IP ?

Caching whether the site is able to speak ECN or not is also suboptimal if the
local site is opening lots of outgoing connections, like a proxy server. (Of
course, memory has gotten cheap)

_And_ it is solving the problem on the wrong end.
