When I was (much) younger and before all this new fandangled thinking (sound like an old fuddy duddy now) came into play, we were always taught to ride our horses 'into the bridle'. My trainers (ok garden variety pony club instructors) never said anything getting 'on the bit'.
The idea was to ride your horse forward into the bridle so he was using his back end to drive the front end and as a result he would lift and lighten the front end thereby raising and arching the neck and giving a more vertical nose carriage.
To get a horse 'on the bit' to me, implies bringing from the front - I may be wrong.
I am a great believer that if a horse is happy to go in something then that is what you use. Youtube some demonstrations of bridless riding,
Unfortunately there are a lot of rules brought about by those who need all the paraphernalia to get their horses appearing to work.
