Privileged clients can change the server base display configuration. Shell wants to know when the base config is committed to a valid config (as opposed to a preview), in order to save that config to disk, to be applied again on restart.

I cannot see any API for shell to learn when base config is changed.

Closest is the AuthorizingDisplayChanger, but that is private. Really, all we want is a callback on
- base config set to new config

Would also be nice to know:
- base config has changed to preview a new config
- base config preview cancelled
