Good, but it means that you don't work or have worked yet on a demanding set and or situation were you don't have the luxury to power down and up ever so often.
Most importantly they are situations were you absolutely need to avoid power down do to luck of power, in the middle of a SHOT.
At which point you either have both the side grip and a V Battery or AB Battery mount as well to hot swap, or you just need to power down for battery change, which in my world of course is not an option, I power down the camera when I want to, not when the camera wants to or needs to for luck of power... ;)
