My oil comes out of the bottom of the oil pan and it has a shut off valve.
I as of yet have no automatic oil change system.
It would seem to me if you had it plumbed into the oil change system the ball valve would be at the pump.
No pressure so little chance of hose failure.
If it gives you a warm fuzzy the next time you are under your motor install one.
Be sure to take pictures and let us all know how it worked out for you
