I hope that this doesn't lead to fracturing the way it apparently did on Mastodon, where every instance that federated with a set of known-bad instances was itself added to the list of "known-bad" instances that the main instances ought to de-federate from (or maybe it will have to be that way to keep out the trolls); to put it another way, I hope that whichever side ends up being the more useful one in this split (beehaw.org or lemmy.world & sh.itjust.works) is the one that midwest.social gets to keep federating with, if it comes to that, or else I'll need to bother joining beehaw or sh.itjust.works directly.
(I forget whether I had to go through an involved process to register on midwest.social, but I know it's not one of the instances with open registration.)
