yesterday I dreamt about a cool feature: A second password, that you can use to make your account start forge. This password can even be public, as the rewards would always go to that original account.
This password would be generated using the passphrase but there is no way to reconstruct the original password using this second password.
Advantages:
No risk when unlocking the account to forge.
Compatible with cold storage
No need to pay fees to lease the account
Disadvantages:
None really, maybe some extra work to implement
