But my idea was to have my headless little streaming Pi connected to my fabulous Wega Concept 51k controlling everything related to playback on my Denon AVR (vial Airplay). An a "nice to have" feature would be to have a volume control that actaually shows the state of the player's volume setting when powering the PCP-Pi.

I believe that's what they did in the project I'd linked to. But thinking this twice, my project would be even more complicated. I realized that I would need one of those motorized linear Alps/Alpine sliders that were (still are?) used in highend sound mixers. See https://www.adafruit.com/product/5466 So the idea is: After powering up the Zero W, it uses the volume status of a determind player, converts it to volatge and send the slider to the correct position. When moving the slider manually, voltage difference ist converted to a volume setting in LMS.
