It had been in the works for a while, but now it has formally been adopted. From the article:
The regulation provides that by 2027 portable batteries incorporated into appliances should be removable and replaceable by the end-user, leaving sufficient time for operators to adapt the design of their products to this requirement.
It doesn’t target phones or tablets specifically, but that doesn’t mean that they aren’t include in “portable devices and appliances”. The sentence you quoted simply suggests that there should be additional regulation on top of the currently pending in the future.
