It is preferred, but does that make the other formats non-free?
Often the .xcf is simply not available anymore, not even to the
creator.  The strength of the preference for it depends on the
complexity of the image and on the exact format (lossy jpeg?
blurred png? reduced palette?).  It's an area where reasonable
people might disagree.

There are also variations in usefulness of a .xcf file.  Does it have
all the layers still separate, or have some of them been merged and
smoothed?  Combining those layers into the final image is often part
of the creative process and is usually not automated.  At least, not
the way I do it :)
