That page says:
Status: Abandoned

That search shows you as the fourth result that it is a rejected feature.

Apparently more people didn't find it worthwhile to pursue that tag 
separately.

Where do you get the idea that a causeway is periodically inundated from? 
There certainly are some that are inundated at high tide, but a lot of them 
are not.

1) If the raised bank crosses a lake or the sea, it is called a causeway.
2) If the raised bank crosses a dry valley or a valley with a smal creek, it 
is called an embankment.
3) If the raised bank crosses a swamp or marsh, it can be called either a 
causeway or an embankment.

Ergo: the English language is fuzzy about the difference.

Even the rendering example on the embankment=yes wiki page is about a cycleway 
crossing a lake.

If you really want to tag them differently it probably more in line with other 
OSM tags, to tag it as embankment=causeway. See e.g. the bridge=viaduct tag.
