aRGB was created for editing purpose, it REDUCE data (bit) lost when the
edit involve shifting of RGB values. With a 16 bit image and no clipping on
both ends, effectively you will not lost any data (16 bits is a lot when
fianlly you only need 8 bits) even for sRGB. I believe aRGB was useful only
on the old 8 bit ages.
This is just my guess, I would like to see the reason why we still need
aRGB.
