Ok, then perhaps I should pose a slightly more targeted question. What are people’s H3 implementations going to do if they get a SERVER_BUSY from a QUIC server? What should we recommend they do (either in applicability or h3 drafts)?

For Azure, we are seriously considering using this as a temporary DDoS protection solution until we can get a more fully functional system in place. I just want to make sure it doesn’t result in awful behavior on the client side.

Thanks,
- Nick

I would strongly oppose that. While there are more general purpose features schedule for v2 and the main driver for v1 is HTTP, a lot of design decisions and discussion consider other uses cases,

Well, I agree with that, my point being that "a lot of" is not equal to "all of the".
