Well the intent was to discourage people from using QByteArrays to store upload data in the first place so as to avoid the same mistake committed in KHTML. Currently KHTML stores the contents of an entire file, no matter how large, into memory whenever a user attempts to upload such files. My attempt to get the KHTML developers to realize that is the wrong thing to do did not get anywhere. Anyways, you are correct. It is pointless to attempt to discourage people from using API that has been available since the creation of KIO.

I have updated the documentation for the original implementation to state as such and encourage developers to directly use the newer http_post method instead. Not sure if everyone will agree with my implementation but it makes it much easier to resend POST data on redirection.
