Yes, it is working great. I’ve been using Byzantium with GNOME Wayland. There were some initial issues with conflicting packages, and I was getting quite frustrated with that, but haven’t had any of those for months!
I’m still careful around running apt-get upgrade though, to not uninstall half my system 
The only issue I currently have is that there is no popup when battery almost runs out (see PureOS Byzantium no longer warns when battery low). That’s survivable, imo.
