This is definitely what I am interested in and have concerns about - look at the growth of .world already. Assuming growth continues, there comes a point where there has to be some major upgrading and additional costs to deal with all aspects of that growth and the complexity and services and requests and compliance that comes with it.

How will data be retained, or won't it? What if an instance becomes unsustainable or the owner decides they no longer want to deal with it all - there's a lot of questions and at the moment it doesn't feel clear.
