May be this rooted in tiff thing? If I remembered correctly, tiff's
spec once wasn't
clear with the premult and it became a problem later although it
supported the flag
lately. The problem seems to be cultural even with Adobe. BTW, I could
be totally
wrong and confused with another issue so please correct me.

I am not against it if someone want to change that. Thus you can be sure
that this will cause incompatibleness.
