That's a good counterexample - thanks.

I was thinking of a somewhat similar example of Stanley Park Seawall
in Vancouver, which is also one-way for cyclists, but is mapped with
separate ways for footway and cycleway. However the Seawall has a
physical separation in form of a small curb between the two modes, so
that's defensible. From Esri imagery it looks like Prospect Park ways
are separated by mode only with paint, so having separate ways for the
modes is not as elegant or arguably correct.

So it looks like we will indeed need a new tag to specify one-way-ness
for pedestrians.
