Stepping stones are not a bridge, any more than they are a ford, although that has been in use a long time.

Why not highway=stepping stones, in the same way we have highway=steps. 

Both can only exist on a foot only way.

In the case of stepping stones, they are often alongside an actual ford for example https://www.geograph.org/photo/14321
