Which is a shame, because in theory it seems like creating a self-hosted instance for your personal account has a lot of advantages (not worrying about the host doing something screwy or abandoning the instance, having full control over who you federate with, being able to customize the interface, etc.)

But that may end up going the way of self-hosted email servers, where differentiating yourself from a spam server becomes impossible and everyone ends up on the equivalent of gmail.
