I misunderstood your case. I think in editors like josm, when you
change the direction of the way, you are prompted for the tags which
could be changed. I guess the same could be done for the child nodes.
The mapper would have to decide which node/tag is affected or not
(including first/last nodes). But I agree. It's an additional level of
complication and the way may contain x child nodes with such tags.

Thanks for pointing this example. But I cannot use it against the
"traffic_signals:direction" new tag because in such cases, the tag on
node is easier to use than creating a relation ;-)
In such case, a "from"& "to" roles can help but the "via" is already
in the "junction" role. I would not repeat it. This would also require
that the "from" and "to" ways are different.

Thank you all for your contributions.
