I must be a dying breed but I will never give any external service access to my bank account. And I still remember the days where you actually had piece of software to run locally for such things. Crazy eh.
I would however have an interest in some of what these fancy new "let us have access to your account" companies are offering. If it was simply software to use 'offline'.
For functions where f(x) is something one would want to program or automate in the digital realm of money, that's where we hope to add value to the experience of managing your finances.
