Swapping to support should count for fill protection

With the role detection in the game, it's pretty clear to tell the Braum assigned mid with a full support item suite is playing support, but this is isn't reflected in the autofill protection. Even though you specifically went out of your way to give up the position you requested for someone else's benefit, the game still punishes you by autofilling next game to jungle or some shit.

What's the point in having role detection if playing that role isn't reflected in the following matchmaking?
