It may have been in the past, but I don't think we can honestly say it will 
continue so in the future. As a simple example, someone may want to load a 
file larger than 2 GB via QIODevice::readAll(). It's probably a stupid idea to 
do that, but with a fast SSD that operation could complete in 10 seconds or 
less.

Asking users to use std:: containers is not sufficient if we don't use them 
ourselves. How would the case above return a QByteArray with more than 2 GB?
