The idea behind this project, was to make it as small as possible and as fast as possible. Yes it does indeed lose many features that jQuery (or Sizzle) provide, but if you need something simple and fast, then I don't see why you should include another 50KB file. I really like jQuery, but sometimes its feature-rich architecture is just slow.
