WOW finally I encounter somebody with the same use case as me in the wild. I thought that would never happen. Except I stream off my 2007 Macbook instead, which is basically just a NAS to me at this point. (I actually do own a Synology NAS but have not integrated it with this existing system)

I hate the UI on Apple Music enough that I don't use iTunes Home Share anymore, but instead run an instance of MPD and then just control playback through ncmpcpp. But to modify tags, add ratings, etc. I have a Screen Sharing session open to the 2007 machine to use iTunes. I have an ongoing project to write a web app that would free me from iTunes altogether, but it will be a while before that's usable.

I don't remember if I ever encountered the disconnection issues you did with a modern machine + home sharing with an older one. The thing that drove me the most nuts was that I could not use home sharing if I was using my headphones over bluetooth. They had to be plugged in for home sharing to work.

My favorite trick was when I figured out how to get the advertisements from home sharing forwarded over VPN, so I could use it when I was on work travel. Unfortunately that broke when I upgraded from Mavericks to High Sierra and I never figured out how to fix it.
