They should extend the principle to laptops, obviously.
Anyway, if most comply, why not make it mandatory? Or are these kind of directives only aimed at picking fights with manufacturers?
Note that I am not suggesting that all laptops should have USB-C chargers, that's a separate directive. I mean user replaceable batteries available for at least 5 years, without requiring major surgery to replace.
The noname replacement batteries also have nowhere near the same capacity that the Apple batteries had originally.
