I've seen some kinda "high design" sinks that do abandon all use cases aside from washing one's hands and teeth-brushing and such—so-shallow-it's-barely-there basin, fancy faucet that sends the water straight out in an arc instead of down, that kind of thing.

I assume, like having lots of mirrored or glass furniture/surfaces, they're the kind of thing you get when all the cleaning (and much of the childcare) is done by "the help", who will just have to deal with whatever unhelpful-to-them design decisions you've made. And when you're in a house that has a dozen or more total sinks, so you've also got a "mud sink" somewhere that's better for utility-type things—and maybe one for each floor, if it's the kind of house that has a utility/laundry room on every floor. Not so viable in normal houses where every sink needs to be a multi-tasker.
