The whole discussion on what the EU is doing has devolved into this idea that everyone will be forced to offer a backplate that pops out and a battery you can remove with your fingers.
The directive is far more complicated, and you will not see that at all.
The regulation doesn't mean batteries have to be made swappable with just bare hands. Common tools and some simple, easily undoable gluing is still acceptable. It gets a battery replacement from a process that risks breaking glass parts, overheating components etc.. to something that can be done by a moderately skilled person with a moderately well stocked toolbox in an afternoon.
