Thanks! After reading the link you provided, I found out that gQUIC's FEC (Forward Error Correction) was removed from IETF-QUIC, which is a minor bummer. But it appears that the removal is not permanent, and that it was removed mainly because it is something that can be added later ("QUIC 1.1") in a backward-compatible way. The other really interesting part was the "spin bit". It's intuitively clear how it could be used by ISPs to monitor the latency impact of their decisions. Unfortunately the cynic in me knows somebody will find a way to use it for fingerprinting. Room 641A really ruined the ISP's credibility in a permanent way.
