it is clear: it will be tagged on the way it refers to. If two ways
have a node in common, you shouldn't tag the obstacle applying only to
one way on this crossing node but be more precise. If you tagged the
node in common it would apply to both ways.

+1, that's how it would be done. Basically there is no particular
problem with this tag here, it is just the same as other barrier-tags
or maxheight for instance.
