Alright, but let's be practical. It's a lot of effort to create and maintain
pairs of roads (let's not call them "dual carriageways" - that's really a
specific type of motorway). Let's imagine this tag is implemented and there
is renderer support. What value do you see in mapping examples 2 and 10 as
pairs of roads rather than a single road with divided=median?

Is the benefit just so you can get more precise with area micromapping?
Let's assume, because it's true, that volunteer mapping time is limited, and
the use of areas to micromap roads is rare, and certainly not expected by
end users. Why is a pair of roads better in 2 than a single, divided road?
