From this Slack thread: https://input-output-rnd.slack.com/archives/CA919E6Q6/p1661278131542139 it looks like `cardano-node` configuration files under https://github.com/input-output-hk/cardano-node/tree/master/configuration may be removed in the near future. Some of our `db-sync` configs rely on those files, like `mainnet`: https://github.com/input-output-hk/cardano-db-sync/blob/master/config/mainnet-config.yaml#L15 The current source of truth for config files is: https://book.world.dev.cardano.org/environments.html
