@bvaughn is this still something that should be added? If yes, should I migrate this issue to React too or link the eventual PR back here for context?

@kartikcho Seems useful still, yes. Let's migrate it to the React repo. Tag me on it so I can give it the right label :)

Done @bvaughn :)
Feel free to change the description of the issue if it doesn't provide enough context.
