When I submit an empty Freestyle job config in the default configuration of Jenkins 2.35, the data is being saved to the disk 8 times. All of them happen in this code: https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/model/Job.java#L1227-L1246

• setDisplayName
• Project#getBuildWrappersList().rebuild (onModified handler)
• Project#getBuilderList().rebuild (onModified handler)
• Project#getPublisherList().rebuild (onModified handler)
• AbstractProject#makeDisabled
• AbstractProject#setScm
• AbstractProject#triggers.replaceBy
• final save()

I think there is not so much sense to submit partial configurations to the disk due to the risk of data inconsistency there. I propose to wrap the selected code segment into a bulk operation
