But they do have a specific use case and that is to provide "advanced knowledge" of a publickey that can be used for encrypting a message to an intended recipient, without the requirement for a third-party CA, and more importantly without prior dialogue. We think it is this that would allow you to communicate a pay-to address to someone without seeing them in a secure way.
