[40K: Space Marine] If completed, would the doomsday device have made a difference?

In the game the inquisition is working on a doomsday device that seems to be capable of instantly killing all Orks on a planet instantaneously. The project never comes to fruition to due to the Okrk invasion, but I can't help but wonder: if the project had been completed and worked as intended, would it have made a difference in the endless threats besieging the Imperium?

Are you kidding?! Orks are probably the single largest threat facing the Imperium, purely because of how insanely numerous they are and how tough it is to eradicate them. Thousands of worlds and trillions of lives have been lost to the green menace and it will only get worse. 

The ability to essentially flip a switch and annihilate the entire ork presence on a planet would be a total game changer. What would take millions of IG several years to accomplish (and not permanently, due to ork spores) can be done overnight without any damage to the planetary infrastructure. 

The amount of manpower and resources that would be freed up to face other threats would be staggering, and could very likely tilt the balance of power firmly in the Imperium's favor.
