Well the good news is that the XFS developer at Red Hat is a very reasonable person at least in my dealings with him. I've asked him for changes to xfsdump in the past and he's always done them reasonably quickly. Although I always was paying for support when I interacted with him so your experience may not be the same.

You know, with Open Source, you don't always get what you
ask for. But you do get a lot of it.

Unlike Closed Source, where you get none of it. There are
exceptions to both.
