It's a fascinating question.
The central problem of any social media platform is content moderation, so a way to enable that should be the focus of any public square.
I tend to think that federation will only work if all mods are willing to admit content moderation is their central job.
If it's going to be a global square, interoperability would have to be very high between instances; or it would need to be centralized.
