@janaiyengar 2^16 is not a large space. Trying to request a UDP port from IANA is an informative way to find out just how small 2^16 is, and how strongly defended a 2^16 registry becomes over time. I acknowledge that we have different IANA procedures than UDP ports, but given enough time, we're bound to hit the limit.

@kazuho That's a reasonable point, and I respect it. My understanding of that consensus call was that it only covered the IANA portion of the issue. But perhaps we should focus on the technical reasons why we want, or don't want, to make the proposed change? :)
