/eth/v1/validator/beacon_committee_subscriptionssignals the beacon node to subscribe for a specific sync committee subnet. One of its inputs issync_committee_indices, which I believe represents the validator’s index position within the committee. Previously we were simply using the position itself as the subnet to subscribe to.
