If it is not implemented anywhere, we should not document it. We document implementations, not specs.
Annex B is implemented by all browsers (this is stated by the intro of this section), so for web developers it'll always work, just deprecated.

This pull request has merge conflicts that must be resolved before it can be merged.
@teoli2003 This has been around forever, so maybe we can decide what is needed?
