Most RAW-capable cameras seem to save 12 data bits (per colour

It's worth noting that one of the points of the original post is
that 12 bits would no longer be enough as soon as you applied (for
instance) and S curve to the 12 bit RAW image in a 12 bit image
editor. As a matter of fact simple bayer interpolation of a 12 bit
image would likely create levels between the original 12 bits.

I was really being slightly flippant about the bit-depth; superficially it seems odd to have the option of using 8 or 16 bit files to accommodate 12 bits of data. I take your point.
