Does this break existing behavior of output on top-level final state appearing in state.output?

Does this break existing behavior of output on top-level final state appearing in state.output?

Yes - I don't see how to maintain the backward compatibility in a sensible way here. This doesn't feel right:

createMachine({
  types: {} as { output: number },
  initial: 'foo',
  states: {
    foo: {
      type: 'final',
      output: 'bazinga'   
   }
  }
})

Configuring some backwards compatible logic at type level (like if types.output is not configured) to match what we could figure out here for the runtime world would be quite clunky
