I need to remove some obsolete owner packages in order to prevent them from being added as auditors (archiving still adds them as auditors, possibly another bug?).
However, after locating its PHID and executing a destroy (./remove destroy `PHID-OPKG-ik43d6ip3qvlrqazgx4s`), I get the following error:
```
Usage Exception: Object "PHID-OPKG-ik43d6ip3qvlrqazgx4s" can not be destroyed (it does not implement PhabricatorDestructibleInterface).
```
So it is, it this moment, impossible to delete them.
Reproduction steps:
1. Create a new owner package at: `/owners/edit/form/default/`
2. Locate the PHID in order to destroy it (I used the `owners.query` api method in conduit, because I could not find it any other way)
3. Execute a remove destroy in the terminal
I filed this bug report as suggested in Q230
