vender prefixes are broken. What happens if the same vendor wants to implement another version of the same (still experimental) property? What we need is draft prefixes. WebKit implements one type of gradient? Great, they define a prefix/property (which could be something as simple/silly as -webkit1-gradient), and anyone who implements the same API is free to use the same property name.
