In order to discover a commit is an orphan, you'd need to prove not just that it does not reach the main part of the history (which is cheap---its parenthood network would be quite limited and traversing all of it is not that expensive) but the other way around, i.e. the main part of the history would not reach it. Do you have a cheaper way to do the latter than a full traveral of the main history? If not, then the cost similar to "git log master" is expected.
