* Settings → Danger Zone. The default is to keep everything: deleting a plugin |

* is often a step in reinstalling or troubleshooting it, and years of |
| 8 |
* submissions must not disappear because of it. Without the opt-in this file |

* WordPress includes this file with the plugin NOT loaded - no constants, no |
| 12 |
* classes, none of its functions exist - so everything needed is required here |
| 13 |
* explicitly. includes/data-deletion.php is written for exactly that: it |
| 14 |
* defines functions and registers no hooks. |
