Especially if you have a tip over. A full tank was a huge impediment to get the ST on its center stand. I can't begin to imagine what a tank bag full of tools would do. Of course mav may not be getting the tank bag for the tools specifically but for lighter stuff.
And speaking of light-er stuff I took spiderman302's advice and picked up an AA battery operated bicycle tail strobe. In the event you're stuck somewhere at night the ST's battery (and lights) won't last long. If you've converted all your lights to LEDs the battery will last slightly longer than not long. If you have a dedicated separate light on the back the battery will last slightly longer than slightly longer than not long. <whew> An AA or 2xAA strobe will last a good while.
