This immediately raises a question: could we use this PSARC functionality to 
recover deleted files? Or some variation? I dont need that functionality now, 
but I am just curious...

Not really. Uberblocks are associated with transaction groups. A transaction group can contain writes to many different files, and those writes aren't necessarily everything that's in a particular file. You might luck out and restore a particular file in a rollback like this, but you'd probably lose a lot of other data at the same time. We don't offer the ability to rollback if the pool can be opened/imported successfully anyway.
