Not only is it rarely used, but it’s also very rarely supported among routers, if at all. I think it’s much more common to split the way near the intersection, creating a very short one-way segment (which can have oneway:bicycle=no for instance). At least in situations I’ve seen, this happens to reflect the situation on the ground, since there’s usually a pinch point formed by curb extensions or other barriers to reinforce the no entry or no exit sign. Sort of a micromapping approach. If there’s only a sign, I would probably still do that as a practical matter, based on the location of the sign.
