Reactive Variables as Local State Solution


I noticed on the following page:

That there is an implication that reactive variables can be used as a local state management solution. However, I’m unsure how I would track these reactive variable changes. For Instance, Redux dev tools provides actions and diffs for each dispatched action. How would I track changes in Apollo Client 3 with Reactive Variables as components get more complex and I begin to debug these changes across my application?

Tried resolve for this in the following comment but unsure if another internal solution exists?
