I wouldn't hold my breath waiting for that.
What you can do is export, choosing Original as the format. So you double the disc space, have duplicate files which will come back to bite you, when you can already achieve alternative renderings with VCs.
I'm always thinking "what if?" Virtual copies are dependent on your catalog. If for some reason your catalog get corrupted, you will loose your virtual copies.
I view having sidecar files as a way to hedge against ever loosing my development work.
