This was also my argument in the past. But you still have cases where
it's not 100% reliable e.g. when the node is between two

The attribute is about traffic signals, you can safely ignore the
pedestrian way (until traffic signals will be common for
pedestrians...) If the tag is placed on a real intersection node, we
can consider this as a mapping mistake and fallback to the old fashion
of mapping traffic lights. But again, I'm not here to defend this tag
but to propose a replacement by a relation.

First, this can controlled by a QA tool and fixed.
Second, read my OP. My proposal is to replace this direction on node
by a relation...
