Is there any place where you collect information about using your BLE5 chips in smartphones/pads and about relevant plans of such manufacturers or open design projects ???
Phone/Tablet manufacturers don't tend to publish such information
Is it a risk from their viewpoint?
You probably have to check teardowns etc, e.g https://www.ifixit.com/Teardown.
Turn the question around: why would they do it?
It's not something that the average customer is even remotely interested in
