As a player that's been around a while, I will never understand the declarations of "we don't need more worlds."

I started on Mateus, when there were frequent calls to simply close/merge it with another world (Balmung, usually) because it was so dead and empty. Now, it's population rivals the high pop worlds.
I moved to Zalera when Crystal was broken off, looking for that low pop vibe again. Now, I can say from first hand experience, it's far more bustling than it was back then.
I've been here through the creation of the new worlds (and data center) for EU. At the time, everyone declared this killed DF by spreading everyone out too much, worlds are dead, we don't need this much space, etc. After only a few years, it was clear they were full to bursting and needing more expansion.

So, miss me with this whole "worlds are dead, why bother" rhetoric.
