That any of the multitude of proposals that have been discussed in this forum time and time again gets implemented. I almost don’t care which one, as long as something is being done. And discussions actually have meaning and can come to a conclusion because also those without whose input all of this is moot let us get at least a glimpse of what their thinking is, and where community input is needed/desired to shape this.
You weighed in on this in context of IPv6, but that very part of the discussion was wider than just IPv6, at least in my understanding also encompassing the topic of “geographic” allocation of clients to servers.
I mean, I don’t even mind if the system really gets enabled to allocate servers to clients based on almost individual RTT, on the contrary, as long as that doesn’t mean we have to wait yet another few years until even the basic problems are being addressed by then-perfect solutions.
The problem is that there were so many proposals, but without feedback, the discussions never came to a conclusion. E.g., one idea was to slowly start mapping requests to a country zone to the encompassing continent zone in a transparent fashion.
