I noticed that while the setup phase is much faster (as shown in the commit
message), the actual rebase performance test regressed slightly by about 3
seconds (from ~2s to ~5s). I don't quite understand what led to this outcome.

Additionally, I haven't delved deeply into the technical details of
`git fast-import`,
and I'm not entirely sure if my approach is reasonable and compliant with the
specifications.

I would greatly appreciate any guidance from those knowledgeable in these
area!
