If you give a "--server" argument to pactl, pactl passes that argument 
unchanged when it calls pa_context_connect(), hence the command line 
argument falls under point 1) in my list, for pactl.

Other applications might do things differently, e g by having a dialog 
box where you can configure the server name, and some are probably 
always passing NULL out of simplicity or laziness. Does that answer your 
question?
