What I have tended to do around the beaches of Gower is to mark the 
non-tidal bit of the beach and the tidal bit as separate polygons, setting 
a "waterway=tidal" tag on the tidal bit.

e.g. http://osm.org/go/euMTH1gJ--?layers=B000FTTT

The Worm's Head tidal causeway is the same:

Of course, it currently renders as beach, so some tweaks to the Mapnik 
template might be nice.
