There were waterproof phones and replaceable batteries concurrently but I don't think this is requiring batteries to literally be hot swappable. I think as long as you can remove the back and the battery with regular common tools, nothing proprietary, that would suffice.
It would be harder to do an IP68 rating with a hot swappable battery. Although having hot swappable battery is a huge advantage anyway. But I don't think that's the requirement here, just so normal people will be able to get the battery out with a screwdriver but not necessarily in 3 seconds so they can replace a battery while they're out and about
All of that said companies exaggerate the benefits of an IP rating. All of these phones are water resistant, not waterproof and even then water damage is almost never covered by the warranty. An IP ratings are only tested once under optimal conditions, in real life the IP rating isn't going to hold up after heavy use or one single submersion in water anyway.
So I tend to think the benefits of IP ratings are wildly overstated. Even phones without them hold up pretty well when submerged in water briefly like the Pixel 4a or the OnePlus 7 or the s20 FE.
The problem is even at the peak of its efficacy Obamacare left 25 million uninsured and $100 million underinsured. And it does literally nothing to curb the rate of cost increases.
The United States needs to join the rest of the OECD and have some kind of centralized single risk pool / single-payer plan . The most simple would be something like Taiwan or the UK or Canada but if they mirrored the French or German system which is a little more complicated but still ultimately adheres to a singular risk pool where everyone has automatically opted into.... It would result in universal coverage, and could stop the cost from increasing.
The US spends an average of about 90% of its GDP on health care come out every other OECD nation covers everybody at between 8 - 12% of their GDP
