Where does it state this? Please provide a reference.
All my FCOM mentions is that if a specific speed is required, use selected. Nothing against clearing unused speed constraints, i.e. 250 below 100 if you have already accelerated. Why fly around with incorrect predictions?
Either way I would not get too worked up about it. Surely you make many more alterations to the MCDU during climb and descent, like sequencing the flight plan when on vectors. That's much trickier than a simple deletion of a speed constraint. If you can't manage that..
