Safety is a consideration
I recently saw an experienced looking cyclist (based on his equipment and attitude) up ahead of me, going up a hill, fall unexpectedly. As I approached him, struggling to get his feet unclipped from his pedals, I asked if he was OK and If he needed help. He was OK and said his chain came off and he didn't need help, despite the fact he still hadn't managed to get unclipped.
As an older cyclist, I'd be sad to break a hip or anything else over a chain coming off. It's pedals with toe clips, MTB shoes, straps not tightened, on my three bikes. Feet are secure and can't slip off pedals, and I can back out of them instantly. Safest setup of all, I think.
