Yes, such implementation will help. There is a need for interface like UART BUS that will probe devices without user space. Serial I/O for input subsystem defines new type of bus and uses dedicated line discipline, but it still unable to start driver by itself and requires call from 'inputattach' to open port, assign line discipline and go to forever wait on 'read'.
That was done mainly because almost none of the serial protocols could be auto-probed, so device initialization/setup was moved out of kernel and thus we have the separate line discipline and inputattach utility.
