The negotiation does not require a separate roundtrip, only a tiny additional message sent by the server. So I'm not worried about that resulting in a measurable perf change. And even if there is one in some super extreme benchmark, then you can still set max_protocol_version=3.0 to revert to the regular behaviour.
