I've thought about it a bit, and now I know I see it more as a
fence=yes tag on the main tag, I won't draw the geometry for the
fence, it's not worth it. But I got some flak from Dee on this as
well. So obviously there are lots of people who think it's bad doing
this.

So I guess the final say is how this is handled by the tools that use
the . If they can handle stuff like this with ease, then I see no
reason to  duplicate a way just to add a fence, or making it over
complicated by letting two ways share nodes or a multipolygon from
multipleways..

I consider over zealous use of multipolygons and node sharing harmfull for OSM.
