Code review comment for lp:~jml/launchpad/create-commercial-ppa

Curtis, I agree. However, that naïvety is present in trunk and, I think, out of scope for this branch.

I am happy to make those changes in a follow-up branch. Although, I would prefer to have a pre-implementation chat, since making this particular code path correct does nothing to prevent future errors or make the current rules for private creation more understandable.
