If an extension installs data in Shopware I have to remember the exactly IDs for uninstalling. A cleaner solution would be, to define an ownership for the data. If I uninstall the extension, the data can be automatically removed. This could be a technical name or the plugin_id with foreign key. So the plugin can be only uninstalled if the referenced data is also removed. This data could be write protected too, so the shop owner can't delete for example important mail templates or media folders.
