> +If a server receives a packet with an unknown connection ID, an unsupported
+version, and is long enough to be an Initial packet for some version
+supported by the server, it SHOULD send a Version Negotiation packet as
+described in {{send-vn}}.
+
+Servers MUST drop other packets that contain unsupported versions.
+
+If the packet is a supported version, and an Initial Packet fully
+conforming with the specification, the server MUST proceed with the
+handshake ({{handshake}}).  This commits the server to the version that the
+client selected.
+
+If the packet is a supported version, and a Handshake or 0RTT packet, the
+server MAY buffer a limited number of these packets in anticipation of
+a late-arriving Initial Packet. In the event the server later generates
+a RETRY packet, this buffer should be purged. Servers MUST NOT send packets

On second thought, the buffer purge might be irrelevant.  If the server processes these packets according to the normal rules once it receives the Initial and replies with a Retry, it would drop them, wouldn't it?  So it should just process these packets after it's gotten the delayed Initial, and do what it otherwise would.
