What is point to that? Game has no hidden information like that. In normal games you can check your deck, but in arena where it is more important to know what you, and also what your opponent have its turned off? You can check on your own, by examine logs or makes notes, so where is logic there?
I strongly propose to change it immediately. It has no value at all. And also make you to see whole opponents deck. Same rules apply.
