One sensible right doesn't overweight the never-ending bullshit coming from them.
And imo this is not a sensible right. To change a battery in phones is easy even now. All you need is heat gun (hairdryer), new battery, phone tape (2$ ali) and 30 mins of your time..
Also watter resistance will take a hit.. I wouldn't sink my phone under watter with detachable back cover even if it had ip68 by producer. They don't even cover it in reclamation now.
