I am not sure if thst is really a problem. Batteries of hearing aids have been replaceable for a while now.
There appears to be a few reason to become excempt from the rules, e.g. medical reasons (if it is in your body safety is more crucial than removability of the battery). So who knows what Apples lawyers will do with this.
"To that end, starting from 2025, the Regulation will gradually introduce declaration requirements, performance classes and maximum limits on the carbon footprint of electric vehicles, light means of transport (such as e-bikes and scooters) and rechargeable industrial batteries."
That's another aspect of the regulation but as far as I can tell (from skimming the actual mandate, or the other summaries I found of it) it's doing both. The release itself says
> Starting in 2027, consumers will be able to remove and replace the portable batteries in their electronic products at any time of the life cycle.
Interesting that it's also introducing limits on EV carbon footprints, but that's not to the exclusion of mandating replaceable phone batteries.
