people use the tag, it will be rendered and used in the other applications.
If we would always map just features that are rendered, we would still have
10 mapfeatures instead of hundreds.

there is a proposal for it since March 2007, you can simply find it by
typing causeway in search.

certain feature. IMHO it is a very important difference that the causeway is
frequently below water (tides). Hence it should be marked different. Also
you can find lots of embankments where there is no water involved, be it for
railway or streets, probably there is more embankments in our db for the
reason of keeping the track even than to keep it above water.
> So I would use embankment=yes.
depends. If it is covered by the tide, I'd use some kind of causeway (either
man_made=causeway or embankment=causeway as proposed in the link above).
