ChildProcessMessageManager, ChromeMessageBroadcaster, and ChromeMessageSender
only implement nsIMessageSender and nsIContentFrameMessageManager. Neither one
has QIs in JS now.
ContentFrameMessageManager only implements nsIDOMEventTarget, which there are
no JS QIs for.
ContentProcessMessageManager implements nsIMessageSender and
nsISupportsWeakReference. The only JS QI for nsISupportsWeakReference is
definitely not happening on this object.

All of these have implementations that only QI to nsIDOMNode and nsISupports, and no one QIs things to nsIDOMNode in script anymore.

SVGLengthList, SVGNumberList, SVGPathSegList, SVGPoint, SVGPointList,
SVGPreserveAspectRatio, SVGRect, SVGStringList, SVGTransformList, Touch,
TouchList, TreeWalker, ValidityState only implement nsISupports, so
there's no point QIing them.
DOMStringMap, FrameLoader, NodeIterator, SVGPoint, StyleSheet only implement
non-scriptable non-shimmed interfaces (nsIMutationObserver, nsISVGPoint,
nsICSSLoaderObserver), so can't be usefully QIed from script.
EventSource, Notification, OfflineResourceList, Performance, Screen,
WebSocket, XMLHttpRequestUpload only implement nsIDOMEventTarget, and nothing
QIs to that in script.
PluginArray QIs to nsIObserver but doesn't expose any corresponding methods.
None of the QIs to that interface seem to be on PluginArray objects.
Range QIs to nsIDOMRange, but there is no JS code that QIs to that.
NodeList QIs to nsIDOMNodeList, but there is no JS code that QIs to that.
XMLSerializer doesn't even implement nsISupports.

The change in browser_net_view-source-debugger.js is needed because we now use WebIDL callbacks for MessageListener, and they add async creation stack frames.

XPConnect wrapper overhead for this interface has been showing up heavily in a
lot of my profiles, in some places accounting for 50ms of the 80ms we spend
getting getting <browser> messageManagers. This improves the situation
considerably.

There hasn't been any traction on this feature, and we keep
paying the maintenance and code size and memory usage penalty
of having this implementation.
We can revive this from VCS history in the future if we decide
to start working on it again. In the mean time, it's better
to remove it.
