You can still develop attributes related to bridging and seizing and control IMHO.
But you have to let it flow freely. E.G. you might start out touching wrists, but a split second later you may be clinched and getting elbowed and kneed. It's a transitionary position mostly, IMHO. I think from the position of a "bridge" you'll either be breaking the bridge, backing out or going into strike, or clinch/grapple.
It is bias to think that the art of war is just for killing people. It is not to kill people, it is to kill evil. It is a strategem to give life to many people by killing the evil of one person.
