I really dont think that this should happen this soon, especially since we now know that there are still two season at least left. Pus Cybertron is not just their former homeworld, but also a smybol of what can belost during a war. Its something that all the autobots feel guilt over. And Optimus uses it as an example to humanity about why they should follow peace and not war. But now that message is goiing to be lost dure to macguffin of the omega lock. Also Primus did tell Optimus that it would take several millenia for him to heal from the damafe that the war did to the planet. He certainly didn't mention that there would be a quick fix out there for them to find. It just feels that the hard lessons that they learnt by losing their home will be cheapened by this.
