We have run into the infamous black screen problem with tigervnc under CentOS7, which prompted me to look into how vnc is configured here.

Am I reading this correctly - root needs to set up a systemd vnc service for every user and display individually? Compared to e.g. CentOS before 7, or indeed any other Linux/Unix system where vnc is completely under user control?
No. Users can run vncserver and attach to them like you could before, or you can run Xvnc -inetd, just as a systemd service/socket pair instead of out of xinetd.
The black screen problem that you mentioned does sound familiar -- I've seen it with VNC clients that don't support OpenGL, with the GNOME desktop (which uses a compositing display manager), it just crashes when you log in.
