+If the packet is a supported version and a 0-RTT packet, the server MAY

+Initial Packet. Clients are forbidden from sending Handshake packets prior
+to receiving a server response, so servers SHOULD ignore any such packets.

+Servers MUST drop incoming packets under all other circumstances.

I agree; this is the same point as the "supported version" above; if reading in sequence, it reads fine, but there's no reason not be explicit. I'll revise once we reach consensus on the other items.
