Is the "Used By" Tab always empty for Pages?

Question

Without (direct) Page Linking, I believe Tridion Sites would never show items in the Used By Used In tab of the Where Used dialogue.

In other words, Pages can use other items but not vice versa.

Is this correct? Would there ever be a case where a Page is "used" in the Content Manager?

Edit: The tab is actually called Used In.

Answer 1

The “Used By” tab in the Where Used dialogue shows other items with references to the current item, but also Local Copies of the current item.

So: yes, Pages can have items in their “Used By” tab.

Answer 2

Another case is if a Page is added to a Bundle.
