That's a good question. I only added it because Apache RAT was complaining (and on check-in I discard the change to remove the Apache header). I think the threshold is whether it is a "creative" work, which IMO I don't think it is (and if all of us can agree, I believe).
There was an old thread regarding this, with precedence in other projects. On Tue, Aug 7, 2012 at 11:43 AM, Andrew Grieve <[email protected]> wrote: > XCode removes it every time it opens the project file.
