However, the controller is currently part of the public API and works well in many scenarios, so it probably isn't going away any time soon. Since ControllerFactory addresses a valid requirement with respect to that controller, I'd suggest that we go ahead with the proposed (typed) version of ControllerFactory and revisit the param concept in a later release.

That's what I was thinking too. If the <param> approach turns out to be taken, then in many ways the ControllerFactory becomes less important because for all those custom dependency injection sort of scenarios, you can actually just use the <param> approach instead (and probably would?). But ControllerFactory isn't painful, especially if it is just a Callback ;-)
