@daltonmatos can you check if this still happens on `main`? the `v2.5.2` was using an ancient `logrus` logger https://github.com/distribution/distribution/blob/0bae7512b274045404499c79a298c6898e6fe179/Godeps/Godeps.json#L14-L18 `main` now uses `v1.8.1` https://github.com/distribution/distribution/blob/cd51f38d537ddef391113dd00d16f9ce8b5f9569/go.mod#L30

Adding this in is not as straightforward -- this is a higher-level API that might need to be added to the [spec](https://github.com/opencontainers/distribution-spec/blob/main/spec.md#api) first, rather than adding it to the registry....

I would love to give this another thought and review soon

Hey @neersighted, would you mind weighing into this PR, please?

This needs a rebase @Jamstah also, friendly ping to @neersighted 😄

> I think that as long as the maintainers don't forsee integrity/architectural issues arising from intentionally allowing sparse indexes (something that can already arise organically today, as I understand it)...

We are waiting for the stable release to be cut. The whole reference effort by OCI has been plagued with broken ideas and endless discussions. There is still one contentious...

This is yet another issue that should be moved and recreated in the new repo https://github.com/distribution/reference Mind moving it there @ipanova and closing this one.

I'm wondering...if we're going to do this -- it seems reasonable -- we should figure out a way to do this across all storage drivers, now just the S3 driver...

This now also needs a rebase.
