Juniper MAG/SA question - re: split tunneling policy and use of JSAM/WSAM

Hello J-NSP and Nanog members Hopefully this is the right forum for this discussion - if not my apologies for further clogging your inbox. Here it goes: Would you consider use of JSAM/WSAM to selectively proxy and tunnel certain applications a form of split tunneling? The traditional concept of split tunnels looks at all traffic Layer 3 and above, versus JSAM/WSAM which looks at application traffic at Layer 7. The context for all of this is from a previous question I put out regarding split tunneling policy on government networks. Thanks!
