 For example, it can check if the data equals the attribute `BasePersistence.bot` (which will be the bot object used by the `Application`) and instead store a placeholder.
 When loading the data, the `BasePersistence.bot` can be reinserted instead of the placeholder.
 Indeed, this is basically what the built-in `PicklePersistence` does.
-### ⚠️ Note
-Although `PicklePersistence` does the 'placeholder' process described above, all the data are deep copied with `copy.deepcopy` before being handed over to persistence. This means that you should store only copyable data on bot parts that will be persisted.
