unchained index - study the characteristics of the appearances

[tjayrush]

Quoting from this post: https://ethresear.ch/t/specification-for-the-unchained-index-version-2-0-feedback-welcome/17406/22

Do you have any data on what percentage of appearances
would be missed if you dropped the transaction tracing?
I would be curious to see that data with “app” contracts
filtered out (e.g., ignore Uniswap internal stuff). It
would be even cooler if we could somehow figure out how
to filter out bots (e.g., MEV bots). My guess is that once
you filter out apps and bots, the number of addresses that
appear only in traces and not in transaction body or events,
is vanishingly small and not worth the archive node requirement.

Delaying this. It will be re-opened.
