Not shown: water wasted from pre-washing dishes or having to run multiple cycles because the new eco-modes don't do the job properly. Also from manually washing dishes because the dishwasher is blocked for longer (and even longer once you add the extended drying time required due to the lower temperatures).
Shown: the regulations actually set minimum cleaning and drying requirements, for precisely that reason - the equipment has to do the job properly.

It's almost as if they already thought this through when making the regulation.
Not shown: the EU cleaning requirements are inadequate in reality which is why dishwashers previously defaulted to higher-energy modes - because those modes are the ones that actually work reliably for users. It's almost like the regulations are ideologically motivated rather than having anything to do with reality.
