I've actually seen AI tools do things very similar to what you've
written.

I didn't say this was slop and didn't make sense.  I quoted the portion
that says that we don't accept anything AI generated, including for
license reasons.  There's still very little clarity about whether AI
code is a derivative work of the training set or whether it can be
copyrightable at all, very especially on a worldwide basis.  We don't
want to end up with a legal or license problem that the DCO was intended
to solve.

The kernel and Git do different things.  Linux generally allows AI and
we generally restrict its use quite heavily.  Linux tries to never break
dependent projects and we don't have that policy.

I appreciate the header being included and agree that it should be, but
it's important we ask questions about the provenance of the code when AI
is used because many people do not read SubmittingPatches (or
contributing documentation in general).

We'd typically use repo_config_get_string or such to fetch the
configuration these days.  If you don't want to fetch it multiple times,
we'd generally read all the config and put it in a struct that we'd
initialize with a function at a suitable time.

There's effort to avoid the global variables because they don't work
well in libraries and we want to allow libgit.a to be used more
generally.  In addition, Rust considers static mutable variables to be
unsafe, so as we add more Rust, we'll need to minimize the use of any
globals.

I don't think it's necessarily a problem to have the comments, but it is
uncommon in our codebase, which is what drew my attention.
