There is no need to wait for such an event. In my opinion what makes this site unique is how it is run rather than the tech. One could make note(s) of how Daniel manages this site and try their hand at mimicking the patterns on existing sites. People could attempt to replicate something close to his methodology, guidelines and levels of engagement on their own self hosted Postmill, Mastodon, Forums, Chat sites, etc... In my opinion there is no harm in having multiple great sites.
