I don't think the situation you describe arises at all. There is never any onus on any mapper to add extra redundant details - and it's ridiculous to suggest otherwise. An example is "surface=asphalt". It's indeed the default. And in most parts of the world, there's no need to map it - and the fact that this tag exists doesn't make any of the implications you suggest come true. But in other parts of the world, it's *not* the default, so it's useful to map it. And in some places (eg, the countryside in my region), there really isn't a default, so it's best to explicitly tag the surface of all roads. Similarly, in a part of the world where it's unusual for, say, public telephones to actually be functional, it would make sense to tag that fact. And maybe, possibly, a mapper who sees that a public telephone has just been fixed might feel compelled to update the database to report that fact.
