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.
Both Samsung and Apple offer 5+ years of software support nowadays. It seems unreasonable to expect much more IMO. Devices don’t stop working after no longer receiving updates, and there is also the option of jailbreaking/installing custom ROMs for those who really care.
