Subprofiles are intended to be multipurpose, and for some purposes it would be desirable to indicate clearly in the interface that certain subprofiles are all subprofiles of profile X.
Given that a profile is transport information, it will always be possible for the receiver to tell which subprofiles are subprofiles of which profile. Surfacing this info in the interface (with keyhash art or otherwise) is thus technically an option for the recipient.
Perhaps we could default the display to sender’s request, and have an override for receivers who are dealing with malicious actors?
