Well, if these areas are legitimate OSM objects, that's one thing. But if they're some mapper's idea of a way to customize the map for his or her (or a company's) particular use then I think they should be removed. Especially if they're causing routing problems.

What are they? What purpose do they serve? If those questions cannot be answered then I say delete them.

I've found quite a few proper roads mapped as closed ways with

far, there has also been a correct unclosed way to represent the road.

I can't think of any method using style rules to detect the case when
there isn't this additional road, but my preference is to ignore these
areas and so avoid messing up junctions on major roads at the expense
of maybe not having a route over unclassified roads.
