I've had occasion to do this when testing/debugging. And I can imagine
experienced users who correctly know that they can safely ignore some
dependencies. So I wouldn't want it to be impossible. But maybe we can
arrange it so that dependencies are installed by default, without a
dialog, unless the user has explicitly requested the contrary.
For example, there could be a checkbox on an early screen saying
something like, "For each selected package, install all of its
dependencies (RECOMMENDED)". The box would of course be checked by default.
