    Description

      https://github.com/mongodb/specifications/blob/master/source/server-discovery-and-monitoring/server-discovery-and-monitoring.rst#checking-wire-protocol-compatibility does not explicitly say to exclude unknown servers from topology compatibility decision, but surely this needs to happen as an unknown server hasn't provided us with a wire version to consider.

      Due to 1584 this is reported as

      Mongo::Error::UnsupportedFeatures: Server at (localhost:27018) reports wire version (0), but this version of the Ruby driver requires at least (2).

      ... which is pretty confusing.
