ARM has done some of that in ARMv8, to be sure, but these advantages are only available in 64-bit mode. 32-bit apps, which will constitute an overwhelming majority for the foreseeable future, can only take advantage of the 32-bit registers and operating modes. That’s a fundamental limitation of compatibility modes – you can’t build a chip that perfectly mirrors 32-bit mode for maximum compatibility but still provides access to new registers and floating point capabilities. The 32-bit version of Angry Birds doesn’t know those options exist, and it can’t use them.
