The manufacturers would be idiots to leave that much liability in the inept hands of their dealership servoce depts.
I know how I'd do it. I'd have something that hooks up to all four bleeders at once, and a brake fluid cap that has a hose attached, and apply a vacuum to bleeders at same pressure as the fluid is pushed, so it doesn't agitate the fluid and cause bubbles.

To get the fluid pumped into the system a the factory, they likely use a pressure or vacuum system.
A factory does not ship a car with no brakes. The car has to make it on/off of several shipping platforms before arriving at a dealer. It also has to be inventoried (parked/moved) at a dealer.
I doubt they use any method involving pumping fluid via the MC piston. Pushing the pedal to the floor or past a certain point while bleeding brakes poses a good chance of damaging the master cylinder seals. Usually, this issue presents itself on older, more badly maintained brake systems. But you shouldn't full stroke any brake MC. Read about it before claiming to have had ZERO problems pls.

The theory is that the bubbles break down into small bubbles....work their way up to the MC piston and sit there.
When you remove the pressure on the pedal, they escape thru the ports, and into the master cylinder reservoir...where they are harmless.

yes. but...probably do the wedging as the car is idling so you can be sure you're getting vacuum assist.
you get vacuum assist for like 1 push after the car is turned off. But if you're fumbling around and pushing the pedal in/out to get the wedge set, you may deplete it.
