We're supportive of the feature and we plan to implement it when we've got engineering resources available to devote to it, though nobody's started work on it yet.

I will also add, FWIW, Safari has yet to support this, and we look to do our best not to create web compatibility issues across the web for these new features. The web works best when we all have the ability to support a feature.
