> Making a receiver choose whether to send an ACK frame with ECN or an ACK frame with a timestamp is not the desired behavior.

The solution is to make additional frames: the (theoretical) ECN extension would define an auxiliary frame that carries ECN counts and the 1wd extension would define an auxiliary timestamp frame.  Both extensions would require these frames to be packaged in the same packet as the ACK frame they correspond to.
