This. One of the common stories in accessibility circles is "curb cuts", the ramps from streets to sidewalks that allow disabled people easier access than a stepped curb. They have utility for non-disabled persons towing roller luggage, pushing strollers, pulling hand-carts, etc. While they were put in place due to accessibility concerns, they benefit everyone.

Accessibility facilities that enable UI automation are the "curb cuts" of software.
