No method to restart a node from DEFUSED state

The cancel_job() function can optionally set the node state to DEFUSED after launch cancellation (selected with the pause keyword). Then there is no method to reignite (see this) the node. There should be also a difference between defuse and pause. Why we take defuse action but not simple pause?

In DEFUSED state we cannot use rerun_node() and update_node(). Also these two functions should be adapted.

A good candidate is to extend the rerun_node() method to handle DEFUSED and PAUSED nodes.
