A few reasons: - Mux is already widely used in the codebase to refer to a http handler mux. - Original meaning of Mux was something which sent a chose one of several inputs to and output. This sends one output to all outputs. Broadcast captures that idea better. - Aligns with similar class config.Broadcaster (see #2747)
