I would also like to see such a feature, perhaps implemented via a command line

The problem occurs for me, when I want to display access restrictions on my map.
access=* can be placed on any area element (e.g. amenity=parking) or it can be
placed on any line element e.g. highway=*

Right now there is no way to tell mkgmap, that the polygon rules shall not be
applied to the line elements. If the polygon rules could be limited to closed
polygons only, than this problem would not be solved completely but to a very
large degree. (There can still be line elements forming a closed loop.)
