Expose SWebBrowser to UMG

Right now its only available in Slate, SWebBrowser is a widget which provides the ability to show HTML content as a widget.

When is it finally available for everyone to use in UMG?
This here was the old question, which was marked as answered, but said nothing exactly about when we can see the feature, it was planed for 4.6, now we are at 4.7 and its still not exposed.
