I agree in general you need a good use case. But AFAIK FS devs are aware of many apps not doing it the right way. So I expected them to have a FAQ entry that shows what this right way is. Ted says a huge performance hit is involved, but nobody has been able to tell why yet. There's also the problem of not having permission to create a temp file.
