I would say proper transitions of power is part of good government. Your phrasing makes it sound like governance doesn't need to be good as long as it transitions properly.
Improper transitions of power cause bad governance.
I guess that in that context, if we reduce the role of government in as many ways as possible then whether a Good or Bad governance would have less impact to us? And in doing so a proper transitions of power is more important?
A bad transition of power usually (almost always?) results in an increase of the role of government. Bad transitions of power requires the new government to assert its power in order to legitimize itself. In the worst scenarios that means jailing/disappearing the opposition/journalists/activists/etc.
That works right until you have a government that does absolutely nothing and the public vote in someone who promises to smash up the system. Someone like... Donald Trump.
