They are unrelated. Larger windows help achieve higher throughput over paths with high delay. You allude to selective acknowledgements as a way to repair loss before the window completely drains which is true, but my point is that no data can be delivered to the application until the loss is repaired (and that repair takes at least a round-trip time). (Then the follow-on effects from noticed loss on the congestion controller can limit subsequent in-flight data for a time, etc, etc.)

The application will hang waiting for the stack, but the stack keeps working and once the drop is remedied, the application will get a flood of data at a higher rate than the max network rate. So the application may pause sometimes, but the average rate of throughput is not much affected by drops.
