Also, as a few other people have noted here, it's actually less expressive than standard notation. There's no way to show phrasing(especially important for figuring out how to phrase 5/4 or 7/4 time), triplets, and I'm not sure how slur/tie notation works(especially because dotted notes are presented as tied notes... not ideal since they're technically not the same thing).
