Right, so by stopping the rendering of boundary lines based on the
relations, that rendering issue is gone. Osmarender has never done any
differently. The relations are not useless. Their name, for instance, is
very useful. So is their admin_level, to decide when, where, and how to
show that name.
That doesn't mean tagged ways are useless and their tags stripped. They do
have a place in the scheme of things.

Many things in OSM don't exactly make technical sense, yet we still use

Oh, the discussion has been going on and off for years now.
