Suppose that an instance of this app is already running and a second

If there's no hand off to get the first running instance to open that
document that the the new second instance should have the second
simply dies when it sees that there is already one running and the
document is not opened.
Mutexes have next-to-nothing to do with the above scenario (aside from
the obvious detection of the second application running).
For a good UI as far as i can see even if the user double clicsk on the
app icon, you would want the new instance to activate the existing one
somehow or send a message to the pre-existing instance to activate
itself...
Thus it would be rare indeed to want only to use a mutex detect the
existing instance and then just quit and not be concerned with the
existing instance in some way, no?
