I don't consider the request unreasonable. It's effectively an "I am done
with this task, you may ask me whether it was successful or what failed
if you really insist" kind of notification that's "good enough" for quite
a few use cases.

As it stands, from a user code perspective, setting up proper communication
with a QProcess is a bit more boiler-plate than one would naïvely expect
from a Qt solution...
