This would be fixed in few releases, such a non-story.
IMO you are less likely to loose your phone then credit card. We think of actual physical credit card only when we need to pay with it. 99% of the time it is just sitting in the wallet being all useless. Phone is something we are using every 5 min or more so chances are less that one would loose phone like that. Now if you do loose it, and hopefully it is locked then no one can use your card. However one can just cancel the card by calling it from borrowed phone or something like that.
As the article notes, they'll have the option to call in and pay over the phone like many other banks allow. It's not ideal, but it's not the end of the world.
