the thought behind this is to be able to call the same method in the UI for different stamps. Another usecase is activities caching, which does not care about the stamp type, but does want to save the descriptor/stampable_name

1) the different caches are set up in Activity::CACHE_CONFIG

2) you can directly go ahead and use a cache, if a object has not saved the cache it will load and save it the first time it is called. The second time it already only calls the cache 🎉

So this can be deployed to production or caches can later be added without having to worry
