> @@ -1116,9 +1146,22 @@ TLS KeyUpdate message.  Endpoints MUST treat the receipt of a TLS KeyUpdate
 message as a connection error of type 0x10a, equivalent to a fatal TLS alert of
 unexpected_message (see {{tls-errors}}).
 
-An endpoint MUST NOT initiate more than one key update at a time.  A new key
-cannot be used until the endpoint has received and successfully decrypted a
-packet with a matching KEY_PHASE.
+An endpoint MUST NOT initiate the first key update until the handshake is
+confirmed ({{handshake-confirmed}}). An endpoint MUST NOT initiate a subsequent
+key update until it has received an acknowledgment for a packet sent at the
+current KEY_PHASE.  This can be implemented by tracking the lowest packet

Makes sense, fixed
