I agree with this -- there is no need to have both. The key thing is
that the application have a library-supplied way to navigate the
pixels -- for current MSG and upcoming GOES-R, the projections are
"fixed", so it would make sense to only define a projection for this
and not supply lat/lon values for each pixel.
