In my opinion, this is indeed the way to go. >I only choose to support 16b alpha (not the 8 bit version (and >don't plan to add it)) I agree. More important than 8-bit alpha would be 12-bit Y'CbCr which is generated by many modern cameras (and the the same sensors are used in some film scanners as well). Hope this is helpful!
