It's official: Smartphones will need to have replaceable batteries by 2027

This is a most excellent place for technology news and articles.
Yeah, I scuba dive and have multiple pieces of equipment with replacable batteries that are good down to 500+ ft. Not only do some of them get opened frequently, and without replacing seals or anything, but they're also all way cheaper than my phone! Anyone who says you can't easily meet an IP68 rating on a phone with replacement batteries is full of shit.
Do those have the same size and weight requirements a phone has? This isn't about "can this be done", it is a question about "which compromises do we have to accept to make this happen".
