It’d be a huge disappointment to see beehaw defederate everything. I’d be even more disappointed if it moved to common web forums or something else. One thing that’s lost is the ability to let other communities in.
I don’t know if it’s possible but you could deny federation by default for every other instance until their mod team sets up a communication line to make moderation easier towards both communities.
That said I suspect this response comes from the recent federation poll where it sounded like a lot of people wanted to federate back into the larger instances again. Beehaw doesn’t have the mod team to really do that and in some ways it’s counter to keeping the space nice since those instances aren’t moderate with being nice as a priority.
