Joystick API

Are there any plans to extend the joystick API to include calls to
identify the type of joystick axis? Like this is an x-axis, a slider,
an rx-axis, etc. I would need that functionality if I were to move
our input code to SDL. If not, I’d probably do the work myself then
to add it, at least for the OS X and Windows implementations. BTW, a
DirectInput implementation is in the works, correct? I wouldn’t know
enough (or want to know:) about the mm API to add it to that
