Yes, GNUstep's AppKit doesn't and I don't think it should.

However, think about a workspace / desktop application, like GWorkspace or
OpenSpace. They usually offer something like "Log out" -- sending a "power
off" note would be the only *clean* way of letting other applications know
that the user is about to log out (ie. terminate the workspace, which would
normally result in 'killing' everything else unless you still would have to
'shut down' the window manager)

Or, again, use -launchedApplications, then iterate through the array and try
sending a termination.

No, GNUstep on FreeBSD (as usual ;-)
