I think there likely is some value here. I ended up building around this issue in house. I do things a bit different… actually poll full logs for block ranges (dynamically based on chain) and track last successful blocks etc. I focus on at least once delivery with idempotent event handling. Partitioning of filters is based on consistent hashes. Offsets are stored for each chain and partition in Postgres. If what you had existed with infura, I wouldn’t have built it. Kafka style consumer groups would be ideal.
