I don't know off-hand whether query-command-line-options even exposes the existence of DisplayOptions (not all of our command line options can be queried), but even if it does, I also know that our current command line queries are not detailed enough to readily expose the addition of a new optional member. I think it would be appropriate for the 3.1 timeframe to add a new QMP command that exposes the display configuration set up at runtime, if only so that the DisplayOptions becomes visible through query-qmp-commands as a bug fix for making this change easier to use.
