The GitHub repo says that Mononoke and EdenFS is "not yet supported publicly". The code seems to be all in the open source repository though, what does the "not supported" mean here?
Improved UX is nice and all, but why would anyone migrate without getting killer performance features like the virtual file system?
We think, and many of our internal users agree, that the UX alone is a worth while upgrade. Since the majority of Git repos don't actually need the performance of a virtual filesystem, the UX is the main sell for them anyway. At the very least maybe it will inspire some UX improvements in Git.
