I mean if you want to know how it would effect me it wouldn't. Posts from beehaw don't even come up, flooded out by more active communities, unless I go directly to the beehaw comms. I functionally use it as a seperate website anyways now, if I ever feel like checking it.
I don't really understand your overall goal talk tho. You want to be nice in an intentionally vague way, but you feel like federation is somehow limiting you from achieving this vague state of niceness... Is it just moderation difficulties (not to downplay them) or is something else about leaving the fediverse door open problematic to being nice?
To be blunt the solution to your problems seems to me the same as every single other time beehaw federation is talked about: the community you want to achieve will require many more moderators than a typical community of equivalent size, they will need specialized mod tools, they will need to be high quality skilled highly vetted mods, and you will need exponentially more of them the more users appear on beehaw. Federation doesn't directly stop you from doing any of that, but it does lead to faster growth, which leads to too much work if you aren't constantly adding moderators to match growth.
You should be asking yourself how big you want beehaw to be, and how big of a beehaw you think can be achieved at all.
Sorry I didn't mean to be this rambly when I started writing ignore it if you want
No it doesn't full stop.
