I just read through that series. All of the changes look like obvious improvements to me.

Correction: the list of packfiles is still essentially on the object
database layer. The change here is that it's not contained in `struct
packed_git` anymore, but instead it's moved into the packfile store.
So packfiles become a standalone entity, and the packfile store is
completely responsible for managing the list of packfiles.

I think the series is already in a good shape after the last round of reviews, but let's give reviewers a few more days to reply to the second version.

I think there's still a couple of comments from Eric on v3 of this series that probably need addressing?

Both dependencies have landed, so this should be ready to be merged now.

Will have another look at v5 of this series. I think it's nearing a state where it's good enough to be merged down.

Thanks!
