I think that the use scene is to ensure that no data remains.
This feature will give users peace of mind.
There is a risk of leakage as long as data remains.
I think that there are some things that users are worried about.
For example, there is a possibility that even if it takes years, attackers decrypt encrypted data.
Or some users may be concerned about disk management in cloud environments.
These concerns will be resolved if they can erase data themselves.
I think that this feature is valuable, so I would appreciate your continued cooperation.
Regards,
