In #178836, while refactoring from a virtual class design to a non-virtual design, the logic ended up such that AdaptiveDelayImpl was always constructed, even if the adaptive delay feature was not enabled. Adaptive delay itself was always disabled if the flag was off, this just prevents the ctor from running at all. @dvyukov
