The idea is to ensure that users are informed about the amount of electricity they're paying for. The number of kilowatt hours drawn from the charger is not the same as the number of kilowatt hours that end up in the battery.

Here's a demonstration on an Ionity charger with a Tesla Model 3:

In the end the charger delivered 65.5 kWh but only 61 kWh was added to the battery. 4.5 kWh is a difference worth knowing about.

Being billed for kWh at all and not time seems like a far more important part of regulation.

All the parts are important. It's regulation that has to be followed.
