yes thats true, but so is open-sourced drivers. it is very limited all right and not flexible but for a closed-source emulator (again, NOT Kawaks) trying to add flexibility, i must admit it is a very clever method. you dont compile DATs, and you dont see what specific codes the DATs correspond to, both true. but for the sole purpose of adding games support, it IS still a driver. the only real difference is flexibility.
