Important point. It's not actually all that trivial to give a good and safe lead belay with a grigri. I see folks wrap their thumb over the Grigri cam to pay slack all the time. It is extremely dangerous when combined with not paying much attention because a surprise fall will cause the belayer to seize their grip on the device and lock it open.
