Worse, it makes it impossible to ask questions like "was this file changed since it was created?" and expect reliable answers. On systems which have no "birth time" you get the answer "no" when the correct answer is "we don't know". > But I guess all findutils can do is go by what stat() > reports, and users must be aware that ctime==btime may be the indicator > that btime is not supported for that file. But I don't think we can do that, because it is indistinguishable from the "file never changed" case.
