Batteries are already fairly easy to replace if you’re not an idiot. A hair dryer, a little screwdriver, a guitar pick, and a 5 minute YouTube video is all you really need.
I guess the EU just misses the days of ugly plastic backed phones that die if they get slightly wet. Or you drop them and the back falls out and battery goes flying across the room.
Gotta cater to the lowest common denominator of humanity though I guess.
