Hopefully never, because hardware will always remain something you can physically lose. For certain people (myself included) that's a much bigger risk factor than getting your password manager db compromised. If I lose my keychain authenticator or what have you, I don't want to be stuck not being able to use any of my websites until a new one arrives.
