> I agree that it seems that a server SHOULD provide some sensible value. My guess -- based on some of my mental models -- is that this number should be between N/2 and N, where N is the maximum number of parallel requests the server allows.

FWIW the maximum we have been imposing is 16, we've been closing the connections that goes above that with an ENHANCE_YOUR_CALM error. I do not think that has caused interoperability issues.
