Part of the idea was that this would be a means of communication between application and provider, just like controls are with libcrypto sub-systems.
The main differences are that we aren't stuck with the limitations of the control functions, that the interface is uniform (if you look at the control functions, they have variety, all depending on when they were crafted and by who), and that you can pass or retrieve several parameters in one go. Also, it's extensible (i.e. it's always possible to add new data types if we feel the need to).
