We are currently going through a more formalised specification process to hopefully get a properly specified version of the scheme I outlined in my talk. While the final scheme might not be the same as the one I outlined (which should be unsurprising given I hacked it together pretty last-minute), the general design should be similar. Unfortunately it will certainly be some time before we can point to production users of such a system.

All the ideas there are great!

But will Docker (or Moby or whatever they'll be called in a week) implement them?

Well, Docker has *finally* implemented OCI image support (which just boiled down to supporting the metadata blobs, since the layer blobs were designed to be identical between the Docker v2.2 image format and the OCIv1 image specification). So it's entirely possible they'll support the extensions we're working on, but I wouldn't hold out hope that it would be a quick transition. containerd and podman/cri-o will probably pick them up faster (though I think podman/cri-o will require more extensive changes to their storage internals since they're based on Docker's graphdriver code).

This seems kind of similar to ostree, have you considered just using that?
