Seeing the rampant confusion this causes when trying to subscribe to remote communities makes me wonder if the full community list could be shipped on initial federation, and community creation/change events could be eagerly shipped network-wide.

I get that in federated/peer-based systems you need to be choosy about eagerly propagating messages network-wide, but the list of extant communities seems like it would be fairly small even on a big server. Like hundreds would be common, and tens of thousands of communities on a big server could still compress down to a message-size of a few KB. Having the /communities/ search and all-communities page do something useful from the moment of federation seems like it would reduce a lot of confusion.
