Add serial to wl_output::geometry?

I'm writing a Wayland client that needs to keep track of screens across reboots. I registered a wl_output::geometry event handler. This event already has the fields "make" and "model", but is missing "serial". Is there a way to get an output serial (something like "HS3P505873")? Would it be possible to add it to the protocol or is it too late? Is there another way to identify screens?
