As someone else said, providing the RAW format allows a reuser to
optimise it for various print qualities, rather than optimising for
screen (and probably smaller file size at that).

And I didn't make that quote up. :) Whether or not there is any
discernible difference, (at least some) publishers feel there is. I'm
inclined to trust them on that point rather than insist that JPG ought
to be good enough.
