But that's not what the regulation is saying, is it?
It says
* replaceable with 'commercially available tools' (which means: Apple could just sell you a 'iphone battery replacment tool kit for 1000 Euros)
* has excemptions for high-cycle / long-lived batteries
* ... nothing about the price of the battery (which can be 1000 Euros)
* ... or that the battery/the battery's form factor can't be trademarked, essentially locking you into 'Apple batteries' and preventing aftermarket ones.
Also, I'd rather have a less bulky phone with fewer mechanical parts that can break as compared to a more user-maintainable. Because of 'high-security' software (think: banking apps, or - I assume - the soon-to-be-released EUId wallet), the thing is basically worthless after four years anyways and needs replacement.
I'd wager that ... nothing at all will change in 2027.
