Well, like I wrote below, it is basically about scaling Lemmy across multiple servers, with all the complexity that entails. I am probably not the best person to given advise on that though.
If our smaller instance ever gets to a size that is not feasible to run on a single server anymore, we will likely close registrations.
This is a planned feature for Pixelfed that is perpetually finally almost finished since about two years now 😅
