Well, badbits are only enforced on the centralized http gateways. LibGen CIDs would still resolve fine using the DHT as the decentralised discovery mechanism

Haven’t played with alternative harnesses. What’s broken in your opinion and what benefit brings pi for you?

Actually, lookup is super fast - CID lookup is consistently <200ms from the EU [0]. The original slowness came mostly from stale records and NAT’d peers that were indexed in the DHT which has since been mostly resolved.
