With the rapid increase in Ethernet and bus speeds, the need for hardware offload has become critical in encryption applications.  Besides the reasons stated by @pravb, from this hardware vendor’s point of view, requiring packet number encryption makes the QUIC protocol less friendly to offload.  It requires an added pass through the hardware crypto engine and depending on the hardware implementation, this can result in a loss of performance or additional complexity.  It would hence be ideal to make this feature optional.  That would have the added benefit of allowing the hardware ecosystem time to mature to support this feature, especially at higher speeds.
