 The QUIC packet size includes the QUIC header and protected payload, but not the
 UDP or IP header.
+QUIC depends upon a minimum packet size of at least 1280 bytes.
+This is the IPv6 minimum size
+{{?RFC8200}} and is also supported by most modern IPv4 networks.
+Assuming the minimum IP header size, this results in a
+QUIC maximum packet size of 1232 bytes for IPv6 and 1252 bytes for IPv4. 

I could live with that.
