I'd rather not: I am trying to keep input API hardware-independent and the kind of device emitting keycodes (a remote control in the sense of drivers/media/rc or USB device or BT device) should not really matter to consumers. Similarly how we do not export whether device is USB1.1 or USB2 or USB3 (although we do have input->id.bustype, but it is more for identification purposes rather than for adjusting properties). For configuration (like loading keymaps) we can examine parent hardware device and decide.
