Actually, the Japanese & Asian model 2 did not have that issue as they kept the model 1 power switch:

Still, the stock model 1 is better due to its better sound output. On some model 2s it's barely 1/4th of the frequency spectrum that gets through. It can be fixed via modding though. TmEE offers a Crystal Clear Audio Mod (CCAM) which allows you to enjoy the very best sound possible from a model 2.
So if you wanna keep your model 2 but want the power switch and sound capabilities of a model 1, buy a Japanese or Asian model 2 and send it to TmEE to get it fixed.
