In the example scenario, that wouldn’t matter because it was established that there was no time pressure. I would consider time pressure to be a complicating factor though, and would call for a check if there was.
I agree that time pressure could indeed be a complication. I already gave an example of being fired at while climbing, which is similar in nature I think. The PC is making an extra effort to get up the rope quicker, which absolutely would demand more stamina and strength to do. How much it would require, is something I would consider an uncertain outcome. Hence the check.
