Note sure I understand the question.

On D-Bus signals are broadcast to the bus and anyone who is interested
can subscribe to them. That can be one peer, or many peers or zero
peers. If you are writing a service yourself, and don#t write a
matching client, then of course most likely nobody is going to
subscribe to your signal and it will just be dropped by the broker.
