Tagging 2 things to represent 1 physical feature just makes it
extra-hard for anyone consuming the data. They'd have to say "OK, I've
got a man_made=embankment here; now, before I decide what to do with it,
I have to see if there is another parallel one facing the other way that
tells me that what I've really got is a raised flood bank or similar"
We represent other linear features (e.g. roads) as lines; it makes sense
to do the same here.
