Maybe that would be useful in some scenarios. In my case it would not
be necessary because I'm using a dispatcher function anyway. I can
already do this with SYSEX messages, no?

SomeController.statusResponse = function(message) { /* handle SYSEX */ }

now I would like to generalize this to

SomeController.controllerMessage = function(message) { /* handle message */ }

If Mixxx could call this method (when it's defined) it would be the
easiest option. It could be made explicit by having a stanza that
diverts all messages like the example in my bug description, but that
would actually complicate matters as far as I'm concerned.
