"something like this" you mean because of the license or because of the small number of files? If the latter, my question is always "what is big enough?". So far I understood we were concerned by any file non having Apache headers. I understand that you can add an entry in NOTICE file, but then wouldn't we just do that for every BSD file? Having a clear guideline on what is required instead of desireable is important, otherwise we tend to aggravate the problem by just adding more files with BSD headers and get lost on how far or near we are to satisfy IP clearance requirement.
