I think it's actually a feature that loss information is NOT explicitly visible with QUIC, because packet loss ratio is a pretty useless metric in the first place. (The 5G people still dream about the "lossless" network, no matter how little sense that makes.) 

With RTT-scale delay information and if we - say - required QUIC to try and negotiate ECN, those two signals (esp. correlated) are much more useful.
