That submission here explicitly references OCI v2. Composefs explicitly
advertises 100% compatibility with OCI. So, there's a set of OCI specs
including runtime and image. As far as I'm concerned you're all one
container world under the OCI umbrella.

We're not going to push multiple filesystems into the kernel that all do
slightly different things but all serve the OCI container world and use
some spec as an argument to move stuff into the kernel.

The OCI initiative is hailed as unifying the container ecosystem. Hence,
we can expect coordination.
