Mark CG-Drafts as unofficial has helped but we need to do more to make it clear that single vendor feature which gets published in WICG doesn't become an open standard by the virtue of its existence.

We think #138 will also be quite helpful with this.

Ultimately we can't prevent folks from being confused, but aspire to help make our incubation states (and implementation status of each more clear).
