Given that Happy Eyeballs (existing versions as well) provides real benefits, but also introduces some interesting caveats surrounding handling of optimistic data, should we have some mention here that helps explain what to do with any optimistic data?
Perhaps something like:
When target_host resolves to multiple addresses, proxies SHOULD use an algorithm such as Happy Eyeballs [RFC8305] to minimize connection latency. Proxies that race multiple connection attempts MUST buffer any optimistic content until a connection succeeds and discard such content for any failed or unused attempts.
