Changes in contentLib.modify?

Enonic version: 7.14.4

We’re using contentLib.modify in order to programatically make changes to specific content after node.deleted event has been fired on the content. Recently, our editors have noticed that this content is now marked as edited in Content Studio. From the docs, this seems to be expected behaviour, but our editors claim that this didn’t happen until a few months ago. Timeline is quite uncertain.

I just wanted to check: Has there been any changes related to contentLib that could cause changes in ie modifiedTime or other aspects that would cause change of behaviour on content edited with contentLib.modify?
