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.
Always buy the “smarts” as a separate device (a media player or smartbox).
Having the product lifecycle and even user requirements of a fast-changing and cheap (and always getting cheaper) element selected on the basis of computing performace and software like the “smart” media player, to those of a much slower changing and vastly more expensive element selected on the basis of size and visual criteria (the actual display) hard-linked isn’t really a wise purchasing decision - it means that in a few years you’re pretty much guaranteed to end up with either a device that can’t support the latest software and hence has sub-standard functionality or paying a “full TV” price because you need to upgrade just that subset of functionality, something which if bought separatelly you could otherwise upgrade for less than 100 bucks.
