Gold gain keystone for supports?

What if supports gold gain got nerfed or support items got an increase in cost, as i do believe supports are very strong. maybe riot could explore a keystone for supports which grants them gold upon doing an active supporting job, maybe it can be based on vision score, assists and or cc score. obviously i would not want this now because supports already get gold for doing nothing expect not dying.

i've played alot of support games in multiple mobas and i would like it if in lol i could somehow gain gold based on performance instead of waiting for it.

Very broad terms and generalisation but i'm not a game dev and its just an idea, execution is what's important, altho i'm sure riot are not ignorant and already have discussed the concept.
