It is by design that we don't mark things as lost until an ACK is received. That is, lack of feedback is not treated as loss to avoid undoing things later when the RTT may actually have changed. Receipt of an ACK is an important signal that the RTT is fine, and that it is actually likely that packets have been lost.

As Ryan asks, what happens that is suboptimal?
