      If Versioned API is requested by the client, the driver will use the hello command for both initial handshake and heartbeats becuase only hello is included in API version 1, not isMaster. Downlevel versions of MongoDB will respond with no such command: 'hello', which doesn't immediately indicate to users that they're requesting Versioned API from a server that doesn't support it.

      If a driver requests Versioned API and the initial handshake fails, we should provide a helpful error message that includes the text "Ensure that your server supports Versioned API."
