Marco,
Yes, but what if the image received is sRGB, but the output will be on a
printer with a larger color gamut. Color corrections can be made to an image
that will often push colors that might be on the "edge" of the sRGB gamut
out beyond the sRGB gamut into the larger output space. I have seen it
happen time and time again. Even a smaller CMYK gamut has a few yellows and
cyans that are outside the sRGB gamut. If the sRGB image is converted to an
output color space that is larger than sRGB, you COULD potentially squeeze
more from the original image. I can prove it.

But you can't go beyond the gamut of sRGB anyway, if your end result is
still an sRGB file. So, whatever seeming saturation gain in ProPhoto RGB
will be scaled back once you convert to sRGB. That seems futile to me.
