Status of Jaguar support?

Is MacPorts officially no longer supporting Jaguar? What happens if you try to install MacPorts on Jaguar? What happens if you manage to install MacPorts on Jaguar -- can you run it? I see changes were committed to the documentation indicating only 10.3 and later are supported. I see several ports including darwin 6 platform selectors that just output a message that the port doesn't work on that platform. If we are officially no longer supporting Jaguar, then MacPorts should decline to install on that OS, port should decline to run on that OS, and we should remove all darwin 6 platform selectors from all ports.
