I’m right there with you Julian. The 1XX response category gets to be another marker pointing us to the lesson the IETF has been learning for the past decade or so: extension points on a specification that no-one uses rust over time and become unusable.

In this case, I think the 1XX problem is more oversight than anything else. The problems in all these cases are tractable, and can be fairly easily fixed. It’s just that someone needs to spend that time.

So for HTTP/2 the state of play is different. There are far fewer implementations, and those that exist are better and more actively developed. I’m happy to say for h2 that we don’t require negotiation of the extension.
