I believe, their history of messaging apps, makes it very difficult to rely on Google in this area. Organizations that are already in Google's ecosystem will probably use it, but I doubt it will have any significance otherwise. As long as you don't have a need to use it towards other organizations it should work (but don't ever expect Google to implement a feature that is requested by their customers).
