What would such an interface provide to its callers?

I wouldn't recommend assuming that Emacs doesn't deal well with large
images.  Changes committed lately already make it deal much better
with vertical scrolling, and doing the same for horizontal scrolling
should be easy.

So my recommendation would be not to base development on this
assumption.

The user might legitimately want not to download large images, but for
that, we already have max-image-size and check_image_size, no?
