  I looked this over again. I still have a number of concerns around this functionality. It really needs to be cleaned up. Especially the wire protocol and UI bits. But I suppose that's what the `EXPERIMENTAL` label is for. As long as we're not committed to backwards compatibility, I think it is appropriate to land in core then iterate. But let's try to fix as much before the end of 4.8 as possible to minimize impact for people who deploy this. The wire protocol and on-disk format compatibility issues should be top of our list.
