To add to this, with those particular cameras(it’s the frame I shoot on), you’re encouraged by the form factor and ergonomics to turn them off when idle to get the most out of the smallish battery, they boot in like 1s. A battery is good for ~350 shutter pulls, I don’t want to use one of those every time I think about taking a picture.

Also, a dead pixel is not a ruined photo, it’s a minor inconvenience in editing at worst. And every photo I take on a FF is getting edited, the gorgeous RAW output is what I’m there for.
