The issue I see here is that there's someone > that does require it for you to accept their code. That this time it is a hard requirement is a first occurrence for me acting as maintainer. In past years we had new code and I asked if the notice needs to be there and asked for resend without it. The reason is that we have git and complete change history, but that is apparently not sufficient for everybody. > The policy is simple.

What if somebody moves existing code that he did not write to a new file and adds a copyright notice? We got stuck there, both sides have different answer. I see it at minimum as unfair to the original code authors if not completely wrong because it could appear as "stealing" ownership. > Looking over the thread, I'm still confused at what the issue is.

My motivation is to be fair to all contributors and stick to the project standards (ideally defined in process). Adding a copyright notice after several years of not taking them would rightfully raise questions from past and current contributors what would deserve to be mentioned as copyright holders. This leaves me with 'all or nothing', where 'all' means to add the notices where applicable and we can continue perhaps with more contributions in the future. But that'll cost time and inventing how to do it so everybody is satisfied with the result.
