For many of the most painful deletion questions, the root problem is that when the software was first made the stakeholders/product-org didn't think about use-cases for deleting things. At best, they assume a "do not show" property can be placed onto things, which falls apart when you get to legal issues that compel actual removal.

>software was first made the stakeholders/product-org

Practically all building, physical and software is made for a purpose first, the process is mainly an obstacle that needs to be minimized. A piece of software is trying to solve a problem just like a door is. It's driven by economics where the recipients don't want to pay any more than they need to and someone is always willing to undercut you by cutting corners.
