That the telephony service open its own dialog for an incoming call
and for a dropped background call, the wi-fi subsystem open its own
dialog for network authentication, the power subsystem open its own
dialog at 10% battery charge, the audio subsystem open its own dialog
for the EU regulatory high-volume warning, the URL dispatcher open its
own dialogs for unknown or contested protocols ... and that the
Bluetooth service open its own dialogs for pairing.

Piping these through a declarative notification protocol can't
possibly do what we want in each case. Whatever technical elegance may
be achieved by avoiding any QML in these services is coming at the
cost of unfixed UI.
