I wish something like this was used for the Signal message history, similar to what WhatsApp does. As it is now, you either have an ever growing message database full of pictures you don’t need to keep around, or you start deleting them and end up with weird gaps in your message history. Keeping a few bytes of data as a placeholder for deleted images would be optimal in my opinion.
