Why do this now? Because we cannot detect the mimetype of an empty file. However there’s probably no need for people to be sending empty files – in fact it’s most likely testing or a mistake. Our logs show that this happens fairly infrqeuently, so we don’t think we need to tell users we are doing this in advance.
