Sure, but what I'm saying is that I imagine a lot of people won't care. The problem in my eyes isn't the association with the frames, it's the association with the cards. By removing the border, you open up room for a lot more acrimonious discussion as it's no longer "these things are bad" and rather "you chose to use a black-bordered card that I consider to be silver-bordered."
Granted, I think that Unhinged caused R&D to look at these cards a bit more closely and that the black-bordered cards in Unfinity are likely to be the most palatable of the bunch, but trusting WotC to not screw up cards is as bad an idea as making a joke about how WotC regularly screws up cards is. This could be a non-issue if they're cleverly made, but . . .
