Targeted signals are possible and are in use in some cases, as they're the
only solution to certain race conditions. A targeted signal does not require
the receiver to add a match rule, since each connection will receive all
messages that are targeted to it.
They are quite rare though.
You can work for years with D-Bus and never see any other than the
NameAcquired and NameReleased signals sent by the bus.
