Create new empty message using Trigger node

While the discussion over change node having ability to delete whole msg properties continues..

I'm wondering if (as probably simple to implement, without side effects and be very explicit) the trigger node could have "new msg object" (or some other description) as one of its outputs?

If this was introduced first, we could use it in front of a change node and then see if we need it integrating into the change node or a more nuanced version in the change node
