Realistically, manually associating ports with specific multicast streams is not a viable option. Each time a new multicast stream is generated, manual intervention is required to configure specific ports to receive the traffic. In a different situation, if Host3 now wants to receive 239.1.1.1 traffic or Host2 no longer wants the traffic, this, too, must be manually configured. Multicast support on a switch needs to be efficient, dynamic, and relatively easy to implement.
