You're not missing anything....A triangulated 4 bar doesn't really need a lateral stabilizer....but, when you really start pounding on a chassis, as I'm inclined to do, a Watt's linkage will prevent any lateral movement. Whether using heim ends or urethene bushings, there is still a bit of lateral movement when cornering...though minimal...a Watt's linkage will stop it... In very hard cornering, just the give in the bushings can be enough to upset the "load" on the chassis... Normal driving, not required! I just tend to get a bit carried away sometimes...
