We don't have the post 1.0 roadmap very fleshed out at this point. The team has been extremely focused on getting 1.0 out of the door for the last year. This took longer than expected, as expected :-)
But I can say that some form of global content discovery is in my personal definition of done for the project. I'm the BLAKE3 guy at n0, and I don't consider blobs done without global content discovery.
But it is a hard problem, and our standards for "it just works" are pretty high.
