Good point. However, an argument could also be made that if a user uses Network Manager to set up and establish the network connections, the user expects Network Manager to own and manage those connections. A logical extension of this expectation is that, when Network Manager is shut down, it takes its connections with it. If the user wants a more "permanent" connection, then the user should set up the connection manually. At least, that's the way I would expect things to work.
