I've two comments on this: first some image format store a rendering
intent, and this setting should be preserved, and the natural place to do it is a
parasite.
And second, rendering intent is a property of a image transformation, but
there needs to be a way to select the actual image transformation, so the
rendering intent _is_ a property of the image just like a image comment
is.
Think of it that way: an image using pseudocolour should probably be
rendered with wide colour spread. This is a property of a the image, i.e.
exact colours are not important. The rendering intent is used to select,
out of a set of colour transforms, one that best preserves this aspect of
the image.
