My edit was triggered by https://wiki.openstreetmap.org/w/index.php?title=Landuse&diff=prev&oldid=1889234 <https://wiki.openstreetmap.org/w/index.php?title=Landuse&diff=prev&oldid=1889234>
edit that claimed that beach is well defined by
"Unvegetated strip of land at the edge of water."

Main problem with such definition is that strip of concrete/asphalt along shore
is not a beach.

I thought about dunes when I claimed that "beach is not
always unvegetated" but now I see that dunes are not considered as part of the beach.
I copied definition from Wikipedia as it seemed far better as it managed to
exclude stuff like

Maybe copying previous definition from natural=beach would be preferable.

So it seems that maybe I managed to improve it, but purely by accident.

Overall I am fine also with older definition from natural=beach, page but I strongly 
oppose defining beaches as "Unvegetated strip of land at the edge of water."
