What happened to All in one surround bars?

I feel like we need more sound bars that do surround sound by them selves. Yes, it's not beating physical speakers but Atmos isn't as impressive as my YAS-106 Air Surround Xtreme or my YSPs or my Polk Surround Bar 6000. I the Q980 and the True X 40 A. Just not as immersive as the older ones.
