The body of the {{signal.name}}_emitter in the stub.cpp.templ suggests that signals can't be simply broadcasted to be picked up by whoever client which has subscribed for signals via AddMatch.
The destinations for a signal should be known beforehand for emitter function to be able to emit targeted signals which IMHO is kind of in contrast with the message bus concept of signals.
I suggest to make the destination bus names optional and in case of empty list simply emit a signal without a destination.
