-Implementations MAY use other congestion control algorithms, such as
-Cubic {{?RFC8312}}, and endpoints MAY use different algorithms from one another.
-The signals QUIC provides for congestion control are generic and are designed
-to support different algorithms.
+If an endpoint uses a different controller than that specified in this document,
+it MUST conform to the congestion control guidelines specified in {{!RFC8085}}.
+
+The algorithm in this document specifies and uses the controller's congestion
+window in bytes.
+
+An endpoint MUST NOT send a packet if it would cause bytes_in_flight (see
+{{vars-of-interest}}) to be larger than the congestion window, unless the packet
+is a probe sent on a PTO timer expiration (see {{pto}}).

```suggestion
is sent on a PTO timer expiration (see {{pto}}).
