Contrary to how this bill is usually portrayed in the news, this bill allows for using screws and gaskets. Those are enough to make a phone waterproof. Lots of other waterproof equipment achieves Ip68 with only screws and gaskets. I don't see why phones should be any different.

You can still have a waterproof phone with replaceable battery through the revolutionary technology of gaskets ;-) There were several models like that already before manufacturers figured out it's cheaper to glue them

The Samsung Galaxy S5 has a replaceable battery and was waterproof, so they are not mutually exclusive options.

Fairphone have replaceable everything and is IP54 rated [0], making it weather proof

Yeah, I honestly don't see the advantage.

What I would ask is that companies that create phones without replaceable batteries, should provide replacement by a reasonable fee (let's say no more than 9% the cost of the phone).

No. There are already phones that can do this. For example the Samsung Xcover 5.

You have that little confidence that engineers can make things waterproof? all it takes is a sealed environment with a gasket and a bunch of screws. Making "clip in" backs that are waterproof is a challenge, but there's no reason that has to be the norm, screws have worked for centuries and don't break nearly as often as clips
