When a user's account is vanished, it's locked globally, but the associated local and global user rights are not automatically removed. Instead, stewards and sysops need to manually revoke these rights.
Since a vanished account is locked and not intended for use again, it makes sense that all associated rights should be automatically removed when the account is locked.
Benefits:
- No need for stewards to manually remove rights, reducing administrative workload.
- Ensures that all rights are removed consistently across all wikis.
