I think it makes sense, actually. I can plug that port into an existing 10G switch and get 5G over that link, which can be a nice sweetspot (10G can be excessive in terms of power/heat) while we can fully saturate one of the 2.5G ports routed over it without saturating the uplink. And if not it will still play nice at 2.5.
