This home page really needs a prominent gateway to the underlying gossip protocol so you can easily find every public repo on the network. Might be antithetical to the cause, though I argue it isn't. Maybe this already exists but I couldn't find it. And if this isn't technically possible, someone needs to solve that.

The pitch is compelling; if the project home page shows that index, I can see a world where this takes the reigns from Github. Otherwise I don't see it.

There is https://search.radicle.xyz/ if you want to search for public repos. But I don't know whether the home page links to it somewhere.
