Hidden secret

I have just watched Dan’s hidden secret video. Can I take it the stacking “hidden secret” means there not going to be any development of a real stacking feature? Moving everything into sub-folders is definitely not a solution. Creating separate folders, for example, for each RAW + .ONphoto just means more clutter, and as I sort sub-folders at top this throws the whole photo sorting out of sync. I really hope I am wrong here and IN1 comes with a real stacking feature.
