I'm not comfortable pushing large, new features into the release candidates without some significant justification. There's another release coming in six months and having time to ensure features are fully baked is important (for example, this hasn't had time to wind its way through several of the downstreams who do significant testing on internal test corpuses). So personally, I'd prefer to wait unless this is a significant blocker for something else.
