IMHO the right thing to do for boundaries that run down the middle of
roads, rivers, or other linear features to use those as members
instead of duplicating the way.

JOSM also has a hidden and undocumented filter feature with which it
should be possible to hide objects you don't want to see.  Of course
this is hidden and undocumented for a reason.
