It just needs horizontal so that you could throw more servers at an instance and improve performance.
At some point a single community will be so active that one server won't be enough , it's better not to split it just so that it will be easier for the software.
I'd argue the exact opposite. We should strive for more instances and for Lemmy's userbase to be spread around. The fact that is scaling out (more instances) is easier than scaling up (beefier servers) is a feature, not a bug.
It's not exactly something that you can force. If X amount of users want to join an instance Y, the instance should be able to provide capabilities to host those users. Besides, horizontal scaling provides other benefits, stability is the main one - if one server instance goes down, others can immediately pick up the slack.
Lemmy.ml did exactly that and is one reason why lemmy.world got to be that big.
Once the server capacity is reached the instance should be closed and people will just go to another one.
I don't understand why people feel so happy about lemmy.world being ahead of the rest. It's against the point of the fediverse and has risks: the instance can be sold, can make decisions to put advertisement etc. It's like people didn't really understand what was wrong with reddit to begin with and how the fediverse tries to be different.
