Is this in response to Quic or just multiple TCP streams? Afaik quic multiplexes everything over a single connection on a single port.
As for fairness, the reality (aiui) is that neither tcp nor udp is guaranteed more bandwidth. It's all up to middleboxes, and I think there are quite a few that assume udp is "less important"/"can deal better with degraded performance" (eg video conferencing, live streams) and instead prefers tcp, in which case there's no recourse. Did you ever observe any conditions like this?
