The question is - is there firmware putting data in these fields that it expects to survive unmodified? Such behavior would be highly suspect (to me at least), but you never know. There ought to be a reason it's been done this way not just in Xen, but also in Linux. IOW may I ask that you at least make an attempt to submit the same change for Linux, to see what the feedback is?
