Here's another response I got from someone from radicle regarding this.

That's a great Q.

Radicle can support a federated model, where known major seeds are connected with multiple smaller clusters. >Radicle supports also completely self-sustaining and disconnected clusters of nodes networked between themselves >within that cluster. And of course any other network topography in between.

There's a promising active proposal to establish a dedicated new Radworks Organization tasked with solving the >incentivization and reward problem for seeds. https://community.radworks.org/t/discussion-rgp-22-start-the...

Additionally, similar to how one can "star" a repo on GitHub, one can "seed" a repo on Radicle. "Starring" a repo is >often a toast of support, akin to an emoji reaction, with little more effect other than that, but in Radicle "seeding" a >project, goes beyond incrementing a vanity metric: it actively supports propagating that project across the Radicle >network. The count of seedings per repo can also be used as a differentiator between original and "copy-cat" ones.
