Seems that excellent results can be obtained from cropped sensors or cropped photos.
Not sure if this adds to the discussion or not, but here is a 50% crop sample from the 5D3. Please excuse the unremarkable shot of the GBH. No noise reduction performed. Default sharpening, LR 4 export to JPEG.
Focal length = 1,680mm (600mm + 1.4x + 2x)
ISO = 6400
Tv = 1/500
Av = f/16
I only took this image to see what the result would look like at that extreme distance, high-ish ISO and lopping off half the pixels. Even with the heavy crop, I think this is passable for web viewing.
