When we were wondering whether or not to adopt the compat layer for openssl that was suggested by NGINX and that does not support 0-RTT, we asked the IETF QUIC WG what their opinion on the subject was, and it was unanimous: "don't do that!". They considered that exposing QUIC without 0-RTT would hurt the protocol's image because it's expected to be used a lot. I think it can vary depending on whether users visit a site often or not (e.g multiple times a day or once a day). We know that on the OpenSSL front it will remain limited. But for libs that don't need hacks, it's definitely important that we try to support the protocol fully. Willy
