Sure, but the reason they're nice to have for that one time that an accident occurs, whether a drink is spilled or you drop it in the sink or whatever.

It's a pleasant nice to have if it is waterproof.

That's just splash damage, which doesn't really equal waterproofing. There are different IP ratings for the two. Splash damage resistance is significantly cheaper and you'll find plenty of models that don't claim to be waterproof, but are still splash resistant. In other words, IP52/IP53/IP54 instead of IP63/IP64: https://www.dsmt.com/resources/ip-rating-chart/
