I don't. But part of the issue with that is fetching the large query's that would be required for that is expensive for the relays that are already struggling with the load and will likely just get blocked. So any solution like that would have to account for that. A possible better solution is each relay running analytics and publishing stats of course this is trusting the relay is being honest about it's stats. I expect we will see more accurate stat tools exist as people love numbers and tracking things especially as companies come in, but I think bc of nostrs design there will always be a higher degree of uncertainty.
