Actually, the JEP states:

  An entity MUST NOT ever make a request to another entity that has the
  same version of the same application as the requesting entity, except
  for extensions that are not supported by the requestor's installation
  (e.g., one "Exodus 0.9" client MUST NOT query another "Exodus 0.9"
  client unless the second client has advertised an extension or plugin
  that the first client does not have).
