The immediate benefit here is then that we would have access to the 
full range of color subtleties created by the rendering engine?

One thing to make this really useful is to make sure it interfaces 
properly with PREMUL and alpha-channel images (i.e. make it really 
useful with 3rd party composition software so overlays, including 
anti-aliasing, ray transparency, opacity, and Halo materials will show

Fair enough: using high definition color specs for image textures will 
be a nice addition, but the ability to get at Blender's internal 
high-def bits for use in post-production compositing will be useful 
right away.

Thanks, Ton!
