I never hang onto a horse’s mouth to the point that I need to “let go.” In the beginning, they are taught to give to the bit (any bit, and actually a rope halter too). Well to each his own. I would not take a horse out on the trail that had the potential to get strong enough that I would need to forcibly make it stop. We’d fix that at home and then venture out.

Hanging on the mouth is a monstrously bad idea.
I concur that home is the place to lay a sound foundation for the trail. And then introduce “distractions” under controlled circumstances. And then on the trail “keep your head a swivel” so you see potentially “scary” stuff before the horse does and engage their brain in something that will give you the control you need when they see the scary stuff.
Just exactly how one does this will vary depending on horse, discipline, venue, rider skill, etc. There is no “school answer” on “how.”
The curb is a communication device, not a set of “disk brakes.” The “snaffle bit Nazis” cringe over any level of leverage. But a curb permits a rider to “whisper” with their hands because the “communication device” amplifies the input. There are times when this is a Good Thing. This presumes, of course, that the rider has the ability to whisper; many, sadly, only know HOW TO SHOUT!!! Learning to whisper (or even not use rein but rely on seat and leg) is something you learn at home, not on the trail.
Once you leave the school and enter the wider world you no longer have much control over external input. Now the rider’s job is to keep the horse focused on what they already know and gain experience in the wider world without killing themselves or their rider.
