So far I didnt really see this issuing being coined in terms of "guidance for conservative ECN use risks low uptake of the ECN feature". If that is the core issue, then an example of overwhelming information is to see support for addressing the issue from a number of QUIC implementations that do not support ECN, and have chosen to do so because of this guidance. 

Since the other text around ECN seems to require per-packet-space counts, and other parts of QUIC require RTT measurement, I'm finding it difficult to see how this is a burdensome thing to implement. But I can only speak to my implementation and experience.
