Absolute mouse position retrieval

We're not using a device driver, it's a very small application that uses XInput2 to wait for mouse events using XNextEvent and when it sees a mouse event it gets the current position through XQueryPointer and transmits that over a serial link to our device. I was just wondering if a similar feature on Wayland exists or it's a feature that will be added/can be added by us one way or another.

Can you expand on this?

Writing a device driver in user-space which connects to X11 or Wayland is not the right way to do it.
