[x] Figure out if moving some init logic for the various subclasses of BackgroundCommand inside the class would simplify the code and avoid BackgroundCommand.from_factory() layer.

douglas-raillard-arm commented 5 months ago

Upon deeper inspection, the from_factory() solution is still better than moving the code from <subclass of Target>._background() to their associated BackgroundCommand subclass, as it typically requires using a bunch of private function/method from the connection type.
