   - `Permissible->isOp()`: use `Permissible->hasPermission(DefaultPermissions::ROOT_OPERATOR)` instead, **but you really shouldn't directly depend on a player's op status, add your own permissions instead!**
   - `Permissible->setOp()`: use `addAttachment($plugin, DefaultPermissions::ROOT_OPERATOR, true)` instead to add, and `removeAttachment()` to remove it (or addAttachment() with false to explicitly deny it, just like any other permission)
