"Worked" is the key word there.
I find it VERY useful to use ProPhotoRGB, a very large space, as my
working space. I convert into that space (and 48-bit color) in Adobe
Raw Convertor, work the photo in that space in Photoshop, and am
perfectly happy to represent the final result in 8-bit space (and send
it to 8-bit printer drivers, the only kind I have).
It's like the way physical negatives could represent a lot larger
brightness range than printing paper could; it was still useful, because
in capturing the real world in a hurry it's hard to be precise, and
because sometimes you have to work with a part of the real world that
exceeds the capacity of the print. So you need the large capability in
the capture and darkroom workflow, but the final result fits comfortably
in 8 bits and smaller color-spaces.
