But it has better performance

They don’t even have same cables on their laptop

That’s why you should use JS

All of your points only considers the community itself, which is not my argument.

I’m mostly approach this from technical standpoint. It’s impossible to have 100% uptime if there’s no horizontal scaling capability. For example on updating version, currently the instance will need to shut down for maintenance until it’s finished and usually there’s still some issue to fix. If horizontal scaling exist, the instance can update server (or add additional one), move the traffic a bit to test it, and then fully rollout if everything going well.

Why not? I don’t see the drawback to develop ability to do horizontal scaling. If the instance owner doesn’t want to add additional servers, it’s up to them. Obviously they paid for it if they decide to add.

Just to be clear, horizontal scaling means multiple servers handling same instance, it can be the backend service to allow handling more traffics, or multiple db to reduce database loads.

Additionally it allows high availabilities, so if one of the backend service is down (either unexpectedly or do rolling update) the other service can still active so the instance can still be accessed by users
