understand why it was done.
For me, the explanations you give are far from being suffient reasons for choosing to replace an unambiguous set of card ids with one that is ambiguous (which has on several occasions led to people mis-identifying a card here) and which makes using those ids more difficult than it need be.
I know how to resolve the ambiguity, as do you and many others. But there are also many, particularly new users, who do not - for those users, especialy the new ones, it can only reflect negatively on the product.
