Today I faced this issue while deploying Composum Nodes to AEMaaCS Publish
(https://github.com/ist-dresden/composum-nodes/issues/237
<https://github.com/ist-dresden/composum-nodes/issues/237>):

What about extending the Content Loader so that it only overwrites in case the
nodes do actually differ?
@Stefan: Have you created any JIRAs about your proposed options?
