IANAC (disclaimer: I Am Not A Cryptographer)

>From my understanding of the issue, it seems that draft-29 does not provide the security guarantees it claims, when in the presence of a high number of received forged packets. In that instance, QUIC provides less security than TLS 1.3. I think that we should fix this issue in QUICv1, since we are chartered to produce a protocol that is at least as safe as TLS1.3.

PR #3789 seems like the right direction to me, especially if folks more knowledgeable in cryptography think it's correct.
