I see now. I guess I did not really have a full understanding of the
purpose of emacs-sync. So, it might be helpful to add a similar
explanation to worg/org-maintenance.org.

I was mainly concerned about complex conflicts that might
(theoretically) occur. But it indeed does not matter if the conflicts
are limited and manageable.

My idea was not to sync that another extra file at all and leave it in
Emacs repo only. But the same will not work for xml and other diverging
files. I now don't see any reason to change the existing state of affairs.
