Whether the benefit, which is mostly the novelty factor, justify the headache of sourcing them and the rule changes is another story.

Oh you want more power eh:
Same idea with external power MOSFETS
On a PCB
In fairness many window motors use a worm drive.
So the holding torque is really about how strong the gearing is.
As long as the stepper has the torque required to turn the worm gear.
Another way is to use a something like a dog gear to lock the mechanism at the stop point.
The advantage with the dog is that you don't inherit the high worm gear ratio because as steppers move faster they operate with lower torque.
Then again could just use a clutch.
