It would depend on what your application is. When you are notified about
nodes being created, if your goal was to inspect them and conditionally
want to register interested when particular nodes are removed, then you
could go with the script job.
If you want to know when any node is removed, then you could move to the
Maya API and use the MDGMessage callbacks directly:
import maya.OpenMaya as om
def node_added(node, *args):
print "added!", node
def node_removed(node, *args):
print "removed!", node
add_id = om.MDGMessage.addNodeAddedCallback(node_added)
rem_id = om.MDGMessage.addNodeRemovedCallback(node_removed)
Now you can receive an MObject and inspect each one to take action.
