Several astrobiologists I know aren't aware of it. Could it just be that someone made a Wikipedia article out of research that isn't widely known yet?

Have a look at the article's discussion. The classification hasn't gone mainstream. May yet, of course, when emphasis swings from 'Ooh, another dozen !' to 'Not *another* dozen ??' as the exo-planet zoo is shuffled onto a 'family tree'...
