I think if Oracle is going for an optimized version of css for javafx might as well go all the way and define your own "language" (might be similar to css) since css has several issues and was intended for HTML not standard app development.

I think it is important to be standard where possible and applicable and darn close otherwise.  That we are not there yet is just a matter of resources and priorities.

This raises the question of what it means to conform the standard. One should not expect a JavaFX user agent to have the same requirements as an browser user agent. A scene-graph is not the same thing as an HTML document tree. If you apply the point in http://www.w3.org/TR/CSS2/conform.html#conformance to JavaFX, JavaFX can comply with the standard. There is still much work to be done in every area from the parser on down to get to that point.
