Do you mean put models completely offline but still available "only" in the backend?
Personally I'm a bit concerned it would take up storage that does not potentially generate income and consequentially only produce extra cost (making this service maybe more expensive for all of us).
Maybe having a save draft option could be a solution? Deleting a model would then display an option for keeping a draft (which only includes images and text and all other settings, but not the files).
Otherwise a lot of people will just start using it as free online backup solution and tings maybe get out of hand quickly.
