No, because then people will do the wrong thing. They will create intricate "ECN black lists" and make their apps set the socket option based upon whether a site is in the black list or not. This is wrong, and allows the problematic sites to continue to be delinquent. If these sites gradually become more and more disconnected from the rest of the internet, they will fix their kit. Other schemes so far have been met with reluctance on the part of these sites. I do not want to condone mechanisms which allow people to make crutches for these broken sites ad infinitum.
