@sridharangirish91, can you please propose some text to https://github.com/boucadair/draft-xxx-ac-rate-policy-discovery/blob/main/draft-brw-scone-throughput-advice-blob.md to motivate the need to have reliability flag? Thanks

I don't think it is possible to distinguish between reliable and unreliable traffic in QUIC. How is rate-limit policy enforced by networks today for QUIC traffic ?

For network to distinguish, the sender would have to set a bit somewhere. DSCP bit, a certain QUIC short CID, IPv6 hop-by-hop option, something.

DSCP values cannot be typically applied for incoming traffic. The hop-by-hop option also faces deployment challenges. I am not aware of any deployments where CID is used by networks to distinguish between reliable and unreliable traffic.

I suggest to remove it and keep the 00 version simple.
