I will throw another hot take: Most people don't want or need "waterproof" (read: IP-rated) phones. I haven't seen people washing phones in the sink, or using it out on the beach, (of course there will be some outliers, but they aren't designed for seawater anyway) nor is it that useful to have in our day-to-day lives.

In my experience, most smartphones, even without water-resistant ratings, do survive accidental spills or even drops. And for cases where it won't, splash resistance would suffice. Claim of water resistance is already kind of misleading, because it's only temporary and only applies to fresh water (river is not "fresh water" in this case). So it's more limited than what companies want you to believe, and people's habits haven't changed anyway. Unless you live in Japan, or you frequently expose your phone in non-fresh water (for which you would need a different kind of accessory anyway), there's practically no reason you should have a IP rated phone.
