This will provide the awareness of named channels in the MessageBus to *any* router within a Spring XD Module. Before, we only provided that selectively (to the "router" sink module). In that case, it was known that the router was at the end of the stream, whereas now any router could return a named channel, even mid-Stream or mid-flow-within-a-Module. I'm only raising this issue so we know for sure we want that "feature".
