In theory something like a !gaming community could crop up on multiple large instances, especially during the mass exodus while instances are getting hammered with spikes in volume.

If that's the case, we'll have fragmented communities across instances. Is there any way besides subscribing to each of them to combine them into a sort of multi-reddit type aggregation? Or is this considered a temporary (albeit important to adoption) problem during the crazy stages?

Clearly coordination and agreement between leaders is needed. I suggested something like that with a pseudo-instance of "@global", for example. However, it seems there is some resistance to the mere idea of globalizing certain popular communities, which I can understand.

Federation comes with its own set of problems, like replication, data volume, storage requirements, and massive overlap.

That last one affects user experience directly, and needs to be addressed. Maybe it will sort itself out, maybe not. If we have 10,000 servers, even 100 almost the same communities means quite a bit of work on the part of users just to decide which ones to join.

We are looking at the human equivalent of a system with an extremely fragmented disk, or database tables with indexes that end up doing table scans.

Periodic re-organization will be necessary to to maintain usability.

Having a global space defeats the point of federation, though, because now everyone depends on a central authority.
