I don't have the access level to mark this as triaged. You will need to propose any patch upstream. The first thing to do would be to open a bug on the Xfce tracker and set a bug watch here on the remote bug. After that you will need to propose your patch on the mailing list.
The automatic setting cannot be removed as doing so would break monitor spanning panels. I would be in favour on a new pseudo-output though, if it does not cause too many problems to implement it.
