Personal opinions follow.

It looks like the only actual use case we have, exemplified by the xkcd strip, is for a star with the left half black and the right half white. There *might* also be a case for the left-white, right-black star.

Everything else, including one-quarter and three-quarter stars, rendering tomatoes or doughnuts or film reels as "glyph variants" of stars, facilitating a right-to-left rating system for Arabic- or Hebrew-speaking environments, or turning Unicode into a standard for rating systems in general, is a complete flight of fancy by comparison to Jörg's original post.

I think in this case, as in many others, one introductory, exploratory proposal would be worth ten thousand speculative mailing-list posts.
