Exactly.
What is the point of the frame acting as a perfect spring that returns the energy ...back up your leg. There does not seem to be any benefit to this.
Stiff frame that deflects minimally during pedaling is faster. Energy spent on flexing the frame is in practice wasted energy as it does not result in forward propulsion.
