We attempted to integrate Sizzle into YUI3, but decided against it for several reasons. Our selector engine is actually smaller in size and faster in many ways than Sizzle.

We were also worried about the issues with Sizzle adding support for "non-standard" selector's that we do not (and will not) support. Our selector engine supports CSS2 & CSS3 selectors, but we don't add "sugar" selectors that are not in the spec. We are under the impression that if you can't use it in a CSS file, then you shouldn't use it to target a not in JS.

We also didn't want users writing code that relies on these "special" selectors, then when a user uses our built-in selector engine, they will fail.
