It's perfectly fine to call readAll(), and it's documented it will read the
default channel. You can choose another channel or you can tell QProcess to
merge the channels. In summary, there's nothing wrong with using readAll().

That's not what it's meant to do and the documentation is clear that they are
separate and you can toggle between them.

We're still talking about modifying the class in question. If you have
suggestions for new attributes that can help convey this message, then you can
propose them to the standard.
