Exactly right. Especially the last two points are important: no mirrors by default and depends which nodes copy and cache your files. The big challenge ahead for them is how to get various implementations (Filecoin ideally) to make it simple to get dependable nodes to copy/cache/return/etc your files when needed. I'm very excited about it and think they will get there, just important to understand the present vs. future of what works and may work.
