An important part of how this works is that you don't have to make that choice right away.

I've been meaning to move to my own PDS for a few months now. Still haven't. Whenever I decide to get around to it, it'll be fine.

I don't think that's the goal? If we got to the point where no service hosts the majority of accounts, that would be a pretty good milestone.

That would indeed be a huge improvement over the current situation, with 98.5% of repos hosted directly by bsky (!)
