FWIW migrating from Mastodon migrates all your followers automatically and you can interact with them just as you did on Mastodon.
You do need to manually recreate your list of people you follow though, from what I could tell.
Once that’s done you haven’t really lost anything unless you were or were intended to be heavily active with the feed on your local mastodon instance. (Vs federation etc)
