It was a story-telling device. It intros Scott, it makes for a nice 2001-ish twirly space sequence and lets us get a beauty look at the new Enterprise.
Having said that, everybody on the ship looked busy when they got back. We know the ships transporters aren't working. Spacedock appears to be a skeletal structure without the space or ability for its own transporters.

After all, we all know the supervisors are usually ones doing the least amount of physical labor.
