Sure.

core.fsmonitor is set to our custom fsmonitor (this causes issues with submodules, at least on 2.24)

core.untrackedCache true

We use index version 4

And a slight hack: our wrapper sets GIT_FORCE_UNTRACKED_CACHE = 1. This forces `git status` to write the untracked cache if it notices a difference. I was too lazy to add a patch to configure that.
