Stop bitching about Auto-Fill.
Auto-fill is a product of a lack of people queuing for support. Back in season 6, this caused bad queue times + making yourself even marginally available for support automatically made you support almost every time. Riot decided to introduce auto-fill to fix high elo queue times, and decided to double down on it to help with role priority issues for all the other elos.
To get rid of auto-fill, you need to fix what it's trying to fix, thus invalidating its purpose in the game, thus allowing it to be removed. Fix natural interest in support, and we won't need a system to force people to support...or in this iteration, force someone to jg so it can force someone to support so that guy that picked mid/sup can play mid for a bit.
