That's protected by Shamir's Secret Sharing the root encryption key, which adds a fairly robust layer of security. It means that (unless you store the key parts in an HSM/Cloud KMS) there's a trade off of having a manual step to get the unencrypted key in to vault's memory.

You can also set up vault to encrypt each shard of the root key with the GPG pubkey for each administrator before dumping them to output. This way, plaintext shards of the root key never even touch the disk or otherwise come into view of anybody other than the intended recipient.
