HomePod Using updated apple watch to control HomePod

i started the song on my phone or watch, then from the now playing screen i changed the source to HomePod

 

I believe this is just airplaying to the HomePod. I’ve been able to do this with the last few updates. The change log on 4.3 made it seem like we were gaining extra functionality to control the HomePod directly, but it’s not the case that I can see.

 

Started a song on the HomePod from my phone and the now playing popped up on my watch
