What are these holes in new ceiling drywall indicative of?

This is an abandoned flip. Is this maybe an electrical inspection done after drywall went up?

I’m not 100% sure but it looks like a poor job of adding recessed lighting in this room and they trimmed holes in the drywall to allow for room to drill through each ceiling joist to pass the electrical wires through. I seriously doubt it has anything to do with a city inspection. Assuming I am correct, it would be easier for a drywall contractor to cut full straight sections for easier replacement instead of 30 small holes.
