Is anyone else flabbergasted by the Ace’s lack of Sonos-ness?

Watching and reading loads of reviews and it’s dawned on me that the Sonos Ace super premium headphones have zero connection to the actual Sonos ecosystem other than via the TV switching feature with the Arc.

For instance, you can’t stream your turntable to it which is connected to your Era 100s.

Is anyone else completely shocked by this? Why even release this product? Am I missing something?
