Would you get rid of a self steering wind vane if you had one?

Our boat was built in 1974, so obviously due to technological limitations at the time the original owner installed a wind vane self steering on the stern. It is a bolt in style, the rudder is stored in the lazarette I have to lower it in the water with the mizzen sheet and bolt it to the bottom of the bracket. Our boat now has an autopilot and I'm wondering if we need to keep the wind vane at all.

Keep it:
-We could steer at sea without having to use any power
-Could act as a backup rudder (though not impossible to makeshift something else)

Ditch it:
-The components take up valuable storage space
-Unable to have a ladder directly at the stern gate; cumbersome to board from the stern.
-Could possibly have a small boarding platform instead.
-I spend more time cleaning rust off of it than actually using it.
-Limited maneuverability when the rudder is in the water; must remove it before entering tight spaces.
