I was so impressed by this DevSummit 2022 Plenary application of using Knowledge to provide high visibility of Enterprise content and relationships, that I think this needs to be an out of the box solution of ArcGIS Knowledge - no setup of webhooks, python, or notebooks needed. I also talked to several at the Knowledge booth at the UC and several thought this was a great idea.
Since the inception of web GIS , I have had questions such as, "who\what\where is impacted if I delete this service?" "What happens downstream if X happens?" Knowledge solves this problem and it would be wonderful if this was a out of the box solution that came with the platform without too much setup needed. It would be preferable to have a option for this to work with both Enterprise and ArcGIS Online as a lot of organizations have both, and obviously the Graphs would need to stay in sync with content changes. So many people I know when I explain this idea say, "Yes, I need that." It would certainly make my life easier.
