Looking at the latest screenshots of the Android 12 Beta it seems that quick tiles now look like the tiles from the lock screen.
I even found a German article stating that smart home devices will be controlled from there: “So wachsen die Quicksetting-Schaltflächen nun zu milchig, farbigen Kacheln an und erinnern an iOS. Hier sollen sich auch Schaltflächen für Google Pay und zur Steuerung von Smart-Home-Komponenten finden.”
In English: “The quicksetting buttons grow to milky, colored tiles and are reminiscent of iOS. Buttons for Google Pay and for controlling smart home components should also be found here .”

I’m definitely going to wait for Android 12 and see if the power menu gets deprecated or not.
