So last I counted there were only four stacks that even implemented the ACK-ECN frame type to _report_ ECN marks. So even very basic support for ECN is (still) missing in most stacks, esp. the ones that are likely going to see the largest deployments.

I don't think any text tweaks we could make here are going to move the needle on ECN support in QUIC. 

What will make a difference if a major stack implements it and reports a benefit. That will likely make other stacks follow.
