I can't see them doing this. They want want PIP or background audio to be a paid features on a phone. You don't need PIP on ipad, as youtube app already supports split view, 70/30 and slide over view so it's not a big loss there.
I feel like PIP would actually lead to more ads and more next video being played on a phone though.
