Thank you for this hint! I hadn't think of this way of handling the case,
and it's way more straightforward than the use of a relation.

I'll amend my OSM edits to use the ":forward" / ":backward" (I favor this
one to the ":left" /":right", where the involved direction would be country
dependent) tag suffix approach.

Is the use of those suffixes documented anywhere, by the way?

Sorry, English is not my language. I happened to use by mistake too harsh an
adjective for a plain objection.
