This is something I'm very interested in implementing for Docker builds. I've tested out CDC for the final image outputs, it results in smaller outputs but requires tuning between saved space versus request count when pulling. For build cache it might be even more advantageous.

Isn't that rather difficult given the `.tar.gz` layers?

[a_t48]

I have a custom pull client/registry/builder that uses a different format, but can output standard OCI if needed.

It also supports .tar but that's probably not very commonly used.

In theory eStargz layers should be amenable to CDC.

[a_t48]

It feels that way, but eStargz is still only addressable as a single layer, or range of one.
