I am. In fact, that very thing came up before in Discord when someone else was wondering about whether they should try the Switch version of the game or play the older version. I mentioned that as well and pokepal brought up the Wii quick start. However, I countered with the fact that doing so has the Wii U GamePad active and I don't really use it or want it on when playing a Wii game so I don't want to start it in Wii Mode that way.
Moreover, I'll turn on my TV and then turn on the Gamepad. In the time it takes me to hit power on the Gamepad to boot up the Wii U and then select Wii mode on the touch screen, my TV screen is still turning from black to picture. So, I have time to get a Wiimote to turn on and aim at the screen. Once the screen lights up then I can select playing Wii mode without the Gamepad. Yes, that does increase the feeling of waiting to get to playing a game but it's still going to feel long to boot up either way so I might as well take those extra 5 seconds to select TV Mode only for the Wii and play the system without putting unnecessary power to the Gamepad.
