Nice optimization to have them on the old epochs, in theory, but it increases complexity that we can't handle right now. Doing it this way will fix 2 issues:
There's a bug in box2 where triangulation fails if you create your feed after you find the other person's. If we just rely on the additions feed (which we create as soon as possible) this should fix itself https://github.com/ssbc/ssb-tribes2/pull/78#discussion_r1151200636
hopefully doesn't even bite us in prod, since people should only replicate additions feeds once we replicate metafeeds, and people will probably only do that once they themselves have groups/metafeeds and therefore called start() and have their own additions feed
