Not sure if i understand correctly, but instances can only show you what they are aware of. This does not really depend on the underlaying software (unless it is specialized, like PeerTube maybe).
Is there a reason why instances couldn't just index and show all the communities from other federated instances?
Right now you have to do this to add a community from another instance:
I don't see why instances couldn't just have an index over communities on all federated instances, so it's a one click action to subscribe to any community in the entire Lemmy fediverse.
If this was implemented it would lower the bar for new users enormously, and encourage a lot more cross instance subscriptions.
How would one instance know that I set up a new instance without a central service?
When you subscribe to a community from another instance, it learns your instance exists and starts sending it messages and receives responses.
