I think my critique is somewhat correct in that you seem to suggest that this change was made to allow for expanding the permissions from one product to all products, which I don't think one can derive from the things we know.

I think I was somewhat wrong in that I may have suggested that you said this was the only reason (which you didn't explicitly) and also in that I dismissed that they factually can use these permissions from other products now, i.e., no matter whether it was intended or not, the permissions set for other products is broader now.
