Why cant we just have Kleptomancy disable Spelltheifs or Vice Versa?

Note: I'm using Spelltheifs for neatness but this would also apply to coin as well

Because of the un-interactive strategy of Klepto + Spelltheifs in proplay we saw Spelltheifs and coin get changed so you need an ally near you to get gold. I think its been two months since the "band- aid" changes were implemented and we haven't heard a whole lot from the team about their better fix. My question is the above title, why can't we have it so that you can only have one of the gold-generating passives? Either by..

1: Giving spelltheifs another passive that prevents Klepto from going off, 2: Making Klepto disable spelltheifs gold 3: If you have klepto you cant buy spelltheifs or coin (similar to the smite + jg item requirement)

I have some counterpoints to some answers that were brought up I within my friend group. This is by no means meant to shut out these answers from discussion and if you have a valid counterargument to my responses by all means.

1. That would be hard to code: Yes it probably would but I don't think it would be impossible by any stretch and even though it might take a while to code, a long in the future fix is still better than no fix.
2. It would Alienate some support play styles: I know that sometimes Sona , Ezreal, and Neeko supports will take Klepto. but I think those play styles are generally more memey than anything else and not seen a lot, (although please correct me if I'm wrong).
3. The changes aren't that bad they can stay: While it does not have a catastrophic impact on supports it still can be detrimental. If botlane goes south and you are rarely ever with your ADC (poked out, keeps getting killed etc.) then the spelltheif changes just accelerate the downard spiral. You can't get gold from hitting champions, and farming a minion wave STILL disables spelltheifs even though the ally restriction is in place, this denies you gold and vision making it harder to come back from.
4. If Klepto disables Spelltheifs what happens if I accidentally take klepto as a suppourt?: Relic shield, no its not great at all but you can still get gold from it, although last hitting as some support champions is a fate I would not wish on my worst enemy, I understand the concern with this one.

I understand that Riot wants to take a slow approach to this as it is centered around such an unhealthy play style, but I honestly just want an update. If there has been an update please link it to me in the comments.

I also added a quick opinion poll but it has a character limit so I had to shorten the words a bit.

Thanks for listening
