App Search API Validation Tool smart app banner

Now when I run the Search API validation tool (link), it tags my smart banners with the message:


Extracted deep link use custom URL schemes. Use HTTP or HTTPS links for the Smart App Banners if you support Universal Links.


Which I understand is the future, but this will break iOS 8 and previous, right? Or is the plan to support Universal Links in iOS 8 too?


Thanks,


Richard
