I introduced kbin to someone today who asked what the fediverse was. I answered for them of course, but it made me realize that the concept is still technobabble for most people. The average joe probably doesn’t care or notice that server A is really talking to server B. Just have them find out on their own and if a mass migration does need to happen from A to B, just make a standard announcement.
This is my opinion as well. I really don’t think that the average end user should be expected to know or care about how federated servers work, any more than I need to know that when I visit a website it uses a load balancer to route my request to one of many servers. Users should be able to create an account and click on links to find and create content without having to understand anything about the technical end.
