Is your feature request related to a problem? Please describe. I understand the problem of enabling biometric. But if it is enabled and then disabled later is it still a threat? I mean will my passphrase still be saved in the app? Or I will be good as fresh installation?

As soon as you disable biometric authentication, the passphrase gets purged from storage.

Oh, great! Any reason to first override the value and then delete it?

That's an additional safeguard measure. It never hurts to be more cautious.
