I was going back and forth on the wording a bit, glad I found something
that you think is a good description :)

Are you familiar with the multi-pack-index and how it's used, by any
chance?

I came here from bup (https://github.com/bup/bup/) and needed a way to
store the offset to find objects in "pure bup", today it only stores
object *presence* and *pack* in its multi-index, but not the offset.

However, it seems to do a bit better in terms of not requiring a single
multi-index, but instead storing it in midx-*.midx files and multiple
can describe the repository state. Why wasn't something like that done
for git as well? It's a bit annoying to have to recreate the full midx
every time a pack file is added, and searching in two or three midx
files wouldn't really be a big deal?

Anyway, that's just an aside, but during all this investigation I
stumbled across this small inconsistency - I'm glad the docs exist at
all! :-)

Thanks,
