I don't think there's anything that would require you to do anything but have the wires into the panel.
But personally, I prefer all grounds and neutrals (except those for GFI or FCI breakers) be made up.
I have never been an advocate of putting in any devices, especially if drywall, mud & paint are to follow rough-in. The devices will always get damages, painted, mudded, and need to be replaced in the end.
