This was going around the DAL boards last week and to not be "kick-offable" someone said you needed to have a JS reservation. Then someone else said you cannot be kicked off the actual cockpit JS but a flow through can still be kicked off.
I think if you can claim ownership to the cockpit JS you are safe. The problem comes if you walk up to the gate and with your dashing aviator charm kindly inquire "Is the JS available?", gate agent says "As a matter of fact it is available," with a slight wink, but in the meantime somone else reserves it via the phone - you are now at risk, at which time the gate agent who mere seconds ago was giving you a sly come-hither wink now says "Beat it deadbeat, you are being cargo optimized."

Bottom line - Have a JS reservation if you don't want to be kicked off the flight.
