Still too early to call but from what I read in the synopsis it looks like battle power doesn't mean too much anymore. These legit dragonball gods seem to run on a different power altogether.
Battle Power does still matter. East Kaioshin & Kibito had Godly Ki, before and after they fused into Kibitokai. (Also Whis has stronger Ki than Birusu, so the Battle Power element hasn't changed TBH)
Goku & Co could not sense how strong their battle power was (Just like they couldnt sense Whis and Birusu in the movie).
Chapter: 439 (DBZ 245), P10.2
Context: as Piccolo and Kaioshin's match begins
Vegeta: “We’ll finally know: just how much is his battle power, which we haven’t even been able to estimate?...”
