If only we paid people to map everything to the detail you specifically need. I've never seen a public faucet that does what you describe, only in American movies in high schools (so those aren't public and most mappers won't know they're there or, even if, you wouldn't be allowed to use it as a non-student). I'm not sure the tagging scheme is the problem here: even if you'd enforce using the right tag by giving everyone mandatory training and exams so they tag everything perfectly, you'd not get this sort of detail necessarily, at least not without doubling the number of contributors as compared to today. (And that's from a German/Dutch perspective, countries which are already pretty well-mapped. In Belgium you probably need to quadruple the force or more.)
