See the path help for 'revoke-prefix'; this behaves the same, except that it

is impossible to fix revocation errors and these errors prevent the unmount
from proceeding. This is a DANGEROUS operation as it removes Vault's oversight
of external secrets. Access to this prefix should be tightly controlled.
