Section 5.2.1 notes the backwards compatibility requirement with existing S/MIME where a sender can create recipient info structures for recipients it can discover keys for.

Should there be an equivalent mechanism to indicate a sender's support for plasma, similar to the way that S/MIME indicates current capabilities? This could be helpful, particularly when sending messages with Advanced Policies.
