After seeing this pattern a few times, I think it would be good to convert it to a macro that calls a statement for protocol_v1/v0 (and later calls a different one for protocol_v2). It would at minimum reduce the code clones surrounding this handling of unknown_version, and we could have one place that is clear this BUG() is due to an unexpected response from discover_version().
