 Of course, since this is an extensible mechanism which will allow us to
 pack as much metadata as we need in one single place, it's meant to be
 stable and not to change in any foreseeable future.

 So, if the Tor Browser can start using __meta.name both on the receiving
 and the sending end, I'm gonna get rid of the "legacy" redundant
 _messageName property in one of the next releases.
