Correct me if I'm wrong, but:

- If you and your counterparty are both using Signal, nothing about the security of your communication changes.

- If your counterparty was not using Signal, your messages were over SMS/MMS and therefore not encrypted in the first place, and so once again, nothing about the security of your communication changes.

Are you seeing something I'm not?
