By introducing the OutputFormatter, RunControls can influence the formatting
depening on the application started. A nice (and intended) side-effect is that
the QML runtime specific formatting will not interfere anymore with anything
else.
It's not yet possible to attach to an external app running a qml
debugging server, because the server is only started on startup if an
env variable is set. Changing this requires action from Brisbane, but
even the current solution works for C++ apps with QML in them.
