Unfortunately the appreciate amount of sharpening is highly content dependant (and to some extent a matter of taste).

If someone is aware of any papers on automagically selecting appropriate sharpening, I'd love to hear about it. ... but this is just getting off topic.
In that case, it sounds like the relevant parameter should also be stored on the image, rather than on the call to the image. It seems unlikely to me that one would want to downscale using one method on one page, and using a different method on another page. In extreme cases (like, wanting to demonstrate pixelation), people can use the current fallback method.
