You're right that this is just a workaround. I guess you could add only the 0x88 error code and return that for suspicions as well, but that smells too much like a hack even for me :)

From a specification language POV, though, _can_ implies that there are other error codes for which the client *cannot* fail over the operation to another node, and I can't think of any :)
