Can make a multi-confirmation process to delete the mint. Here's an example of a session of windows a user would go through to do so.
- delete mint
-"Are you sure? This guarantees loss of funds my doing so. Please sweep from mint before going further".
[Proceeds further]
- "FINAL WARNING! Deleting mint will cause permanent loss of funds!!!"
[Proceeds further]
- "Fine. You want to delete mint with funds in. Please confirm by typing exactly the mints URL & current balance to confirm mint deletion"
