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.
Yeah, what happens is that it takes effort to keep supporting multiple OS versions. iOS has a history of users being like 90% on the newest OS every time there’s a major update, so a lot of companies only support one previous version beyond the current.
Android is a different matter. It has always been a fragmented mess and new OS adoption has always been very slow (it’s faster nowadays though). Because of that Google maintains a set of libraries that make sure Android features work the same way across multiple versions, which eases the burden on developers.
