> This type of datagram never harms the conncection, because the draft requires the receiver to process each QUIC packet as if it was received as a separate datagram.

That is not necessarily true because that is under a cooperative assumption. Any party that keeps dumping invalid packets might be flagged, also otherwise competent QUIC peers. Seeing something suspect in a packet is reasonable cause for rejecting the entire transmission.

Hence, if this is considered a good idea, both endpoints should understand  and agree  on this and avoid confusing each other.
