 A sender that does not use pacing SHOULD reset its congestion window to the
-minimum of the current congestion window and the initial congestion window.
-This recommendation is based on Section 4.1 of {{?RFC5681}}.
+smaller of the current congestion window and the initial congestion window, as
+recommended for TCP (see Section 4.1 of {{?RFC5681}}).
+
+A sender MAY implement alternate mechanisms to update its congestion window
+after idle periods, such as those proposed for TCP in {{?RFC7661}}.

As formulated this does not permit bursts up to a decayed cwnd because init cwnd is required if not pacing.
