IMO, a relation helps here because you can define the route which the
rule applies to - it only applies going "from" a certain way and "to"
a certain way, and specifically applies at a given "position".

Then it is just a matter of choosing what type of relation works best,
or creating a new type.

Personally I've always seen highway=stop on a node, and I'm not sure
:lanes tagging makes sense on a node (a point doesn't have lanes).
You'd definitely need to add at least direction=forward/backward if
tagging a node. But I wouldn't be opposed to that scheme in general.
