Is a firewall reactive, depending on alerts and updates?

Classic firewall advice is to block all traffic except that which you know
you need. Unless your needs for open ports change, in what way would a
firewall require alerts or updates? [Except to fix its own flaws, perhaps -
but I don't think that alone makes it 'reactive'.]
