> Application specific credit card numbers really needs to be a legally required thing.
My latest card (debit) one has a feature I've not seen elsewhere, but I think kind of solves that too. It has a new CVC number every 10 minutes, which I kind of both hate and love. Love it for the obvious reasons of "not even having the physical card lets you use it digitally" but also because I cannot have it 100% in my password manager, I have to use the banking app to get the latest CVC code when I need it.
I’ve want a physical one of these that changes both the CVC and the entire 16-digit number. Heck let the name submitted with the number be a longer checksum that can be verified at point of sale to figure out who’s actual account it is.
Plus then my gibberish name on my card number will match the gibberish secret question answers.

That's going to be one hell of a lot of an issue in practice. Hotels, car rentals and AFAIK even some airlines want that the name of the card holder matches the name on the ID card.
