Extremely low...close to none. Imagine a pair on a bicycle wheel and what would happen to the balls with no cage once you sit on it. The inner races will push on the balls, forcing all of the balls together and creating a gap between the balls at the bottom of the bearing where the balls are needed most.
...and this is only static load.
I don't see this having any practical applications.
The cage in a bearing keeps the balls equidistant relative to one another.
