IIRC what @mirjak says aligns to what I remember as the outcome of Kista.

I think it makes sense to encourage receivers to send back ACK frames with ECN counters, because without that, a sender cannot use ECN.

Whether a sender should use ECN is a different issue, and for that I prefer not having a recommendation.
