Totally agree. Feeding through a Grigri in order to lead belay necessitates disabling the autolockimg behavior of the device and creates an opportunity for a fall to the ground if the climber loses it unexpectedly. Belaying with an ATC still isn’t a replacement for vigilance, though. Catching a lead fall with minimal fall distance requires a combination of constant attention, deep understanding of the route, its cruxes, and your climber, anticipation of the fall based on your observation of the climber, and bulletproof mechanical memory of the process. Even still, runout is a thing on many routes. I would add on to your statement; the most dangerous part may be the drive to the crag (or perhaps, a scramble approach) but the second most dangerous part may well be the climb to the first draw.
