I think coastlines are really a big exception and everybody can understand that. If we have proper "inner" and "outer" roles, direction of the ways is not required for computing and simply requiring it to make people into better coastline mappers seems a bit over the top to me. The logical consequence of your above statement would be that we should drop rendering of simple areas (without holes) unless they're drawn clockwise! Also, my idea would allow a way to serve as an "inner" member of one multipoly at the same time as as an "outer" member of another; I think you couldn't get that with evenodd.
