John Carmack updated his .plan file with an argument starting off with "We need more bits per color component in our 3D accelerators." The rest of the update explains why. Here's a clip:

" I have been pushing for a couple more bits of range for several years now, but I now extend that to wanting full 16 bit floating point colors throughout the graphics pipeline. A sign bit, ten bits of mantissa, and five bits of exponent (possibly trading a bit or two between the mantissa and exponent). Even that isn't all you could want, but it is the rational step. "

Check out the rest of the fairly lengthy update right here.
