The draft looks fine to me.

The server gets to have a definition of what it means for something to be "too similar" for a request and there is no way for this standard to be communicated to the client.  Thus the client's idea that similar means 'the same payload' may not be the servers idea of 'any payload'.  I don't know how to fix this so I expect it to be ignored.

The document appears to say that this response code is for dealing with a single client.  That is the traffic metric is calculated individually for each client.  The proxy for each client presumably being source IP, port pair.  If the traffic metric is calculated for everybody then it should return 5.03.  If that is not the intent then this needs to be made clearer.

Note that a client could get this as a response even on its first request if the path to the server goes through a proxy agent.
