The purpose of this is not clear to me either. I read the linked document, but I'm not sure if that's supposed to explain it or not.

It is risky to expose a feature to the web. If this is something to do with extensions, why not make it a JS API within your extension framework? If you want a callback to be invoked whenever something happens, then the way you do that on the Web is via Javascript, not CSS. If this has no use on the open Web, then it should not be exposed there. If it does have a use on the open Web, then it should be proposed to the W3C/WHATWG.
