I was pleasantly surprised that this reports messages sent to iframes as well as messages received by the top frame as well. As others said, if you don't see anything in the devtools console, you probably need to pull out the sidebar to look at the verbose/debug log level. A good example case is the youtube embed API (you can find examples on codepen). It would be very helpful if this logged a bit more information about each MessageEvent rather than just the data...like the origin, source, ports and lastEventId. Currently it seems to log the window title, but perhaps the window url or origin would be more useful.
