Because none of the editors had a "reverse way" tool :-). I think JOSM
could reverse a segment, but that's was about it. Figuring out the
direction of a way was generally somewhat challenging.
It's still useful if you happen to have another direction dependent
tag which would otherwise conflict, but I can't actually think of one
right now.
