Please see my other comment. The community is still forming around this and working on setting up the proper fork. This project is not yet ready for announcement.
You are technically right, but I think it's a pretty broadly practiced convention.
It looks sloppy. Wanting the avoid the appearance of sloppiness should be sufficient motivation for the team to do the pretty minor amount of work to add a functioning redirect.
In this case it's relevant, because the Phorge page links to the parent domain for the "Phorge is developed and maintained by The Phorge Team" line. Makes it a bit harder to trust said maintenance.
I'd love to see this successful, but the base domain being down shakes my confidence...
