I know this is kind of a tangent, but I've had a goal of making it easier to self-host an instance since like 2018 and I am *finally* closing in on that
which, I guess more than being a tangent, may even be in opposition to what you're pointing out about bsky, since the logical endpoint is many thousands of tiny instances
edit: sorry didn't mean to hijack, point being I want to make what you're doing easier so there are more yous
