Can be useful for things like a password manager, where bip32 pubkey from DIY can be used to generate ecdh symmetric key.
Then host can encrypt any data and store it in the cloud, and only DIY will be able to decrypt it.
Before decrypting DIY can display metadata attached to the encrypted message, so user knows what he is decrypting.
