Finally impossible picture are not sensitive to light any more when ejected
As I am in pioneer program - I have already tested this film - and it is true, you don't need to shield pictures any more.
IMHO - biggest problem (beside price ) is solved.
Only thing is that you need to wait picture to develop quite long, around 20-30 minutes, but quality of pictures and colors are very good - comparable with instax wide.
Next step should be to put this protecting layer in B&W films also.
