PKDrawingReference missing in IOS14?

Does anyone know if Apple intends to deprecate PKDrawingReference in iOS14? It seems to be missing from the betas, but I cannot find any notes that say it is being intentionally removed.
Interesting, I never saw this type. Seems to be an old name. It seems you should just us PKDrawing instead now.
