I think they were working on a more elegant solution for gold generation items after they pushed the whole "No gold unless teammates are nearby" crap to stop this from happening top lane.
Kleptomancy and support items are just a mess. Newsflash, CSing is an important part of the game that forces laners to interact. Getting free gold for doing something that doesn't require you to interact is dumb.
Kleptomancy needs a rework or for something new to replace it, and support items in general need something to make it so that other lanes stop getting them nerfed for the supports. Maybe only grant gold if you're the person on your team with the lowest CS or lowest gold amount? Or just buff support base stats, nerf their scaling, and let assists on minions grant a small amount of gold URF style so the support gets comparable income to everybody else, but doesn't scale well with that gold. They'd still be encouraged to buy items with active effects or heal/shield power because their scalings would be bad, but they'd have gold.
People are gonna immediately jump in and be like "Supports have more income than they've had in years be grateful you're getting any gold, it used to be terr-" Shh. Problems like this one aren't going to stop until free gold is addressed. Even if they nerf Kleptomancy and support items again, there's gonna be some dumb strat where a jungler grabs a Relic Shield or something to roam and execute every cannon for gold funneling.
