In researching your release notes recently, I came across the following:

#125463, 125593, 133145, 126648, 142340, 147493, 157092, 167300, 172181, 176433, 178583 - Support to automatically re-route the line around the nodes if any nodes is found in between line is added

Does this feature address the following scenario:

In case 2 above, I moved Task 3 between the other 2 tasks - the connector did not re-route.
In case 3 I manually re-routed the connector.

Is it possible to have case 3 happen automatically?
I was hoping that is what the feature I found did.

Any suggestions?

Hi Jim 
By using routing constraints in diagram we can able to do  Line routing for nodes. Please find the below code snippet for how to use the routing constraints.  
                    nodes: nodes, 
                    width: "100%", 
                    height: "100%", 
                    enableAutoScroll: false, 
              constraints: ej.datavisualization.Diagram.DiagramConstraints.Default | ej.datavisualization.Diagram.DiagramConstraints.Routing 
We have created a simple sample for your requirement . Please find the sample in below playground link 
For more information about diagram constraints please find below UG documentation link  
If you want routing for only specified connector instead of whole diagram means then you can define routing for only specified connector through connector constraints. Please find below code snippet for how to enable routing for specified connector. 
            var connector = { 
                name: "connector1", 
                sourcePoint: { x: 100, y: 100 }, 
                targetPoint: { x: 200, y: 200 }, 
                constraints:                                         ej.datavisualization.Diagram.ConnectorConstraints.Default | ej.datavisualization.Diagram.ConnectorConstraints.Routing 
For more information about  connector constraints please find below UG documentation link  
Note: Routing does not support for the nodes inside the swimlane
