No, I'm not arguing for anything, and I definitely don't want to forbid it (I'm unsure how you got that from what I said).

I was just wondering if there was any specific reason why you were encouraging it in this case (I don't think I've seen you ask for it before, though I admit I wouldn't necessarily notice).

I agree that this is true for older code in the repository (pre-git in particular).  I think we should be discouraging new commits with unclear provenance, though.
