This is the challenge. I'm pumped for what they have to say about eventually consitent systems..:

Huh, they didn't solve it - network partition recovery.. or rather their solution is not central sounding to the protocol and sounds like "good luck"

In the event of a network partition, a subset of members may be isolated from the rest of the group long enough that the mechanisms above no longer work. This can only be solved by sending a ReInit proposal to both groups, possibly with an external sender type, and recreating the group to contain all members again.

MLS has features scuttlebutt groups don't have yet, but it's exciting seeing we may have worked on something novel
