It certainly has a lot of overlap and is a very interesting project, but like most projects in this space, I feel like it's already doing too much. I think that might be because many of these systems also try to be user facing?

E.g. it tries to solve the "mutability problem" (having human readable identifiers point to changing blobs); there are blobs and collections and documents; there is a whole resolver system with their ticket stuff

All of these things are interesting problems, that I'd definitely like to see solved some day, but I'd be more than happy with an "S3 for blobs" :D.
