That page says:
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

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
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.
