true - Webkit is the only browser with full support at the moment. Apple/Webkit team were the ones to bring it to the spec.

Mozilla added support recently, and support has been promised in IE10 and the next Opera release. To me, that spells 'web standard'.

Lots of things get promised in IE that don't wind up being very complete, and it'll be quite some time until the IE7/8/9ers fade away.
