Ground is very important in any PCB design as you do not want to design in a ground loop which can cause added parasitics which can corrupt the board or have floating multiple grounds. Using a PCB layout simulation tool which includes all the vias will help insure operation of board as intended.

Hi @cblair ,
The vias you see are ground vias and they are present to insure that the board is perfectly grounded when mounted to a housing or chasis.🙂
