Yes. The possible range of involvement is massive. The question I
would find more interesting than a binary flag is who was doing what
part of the thinking at each step of creating the patch(es).

You can use agents to draft code, make tests, run experiments, analyze
data, and review for bugs. The human can apply a high level of
direction, scrutiny and steering on each of these steps. Or they can
just not do any of that and still get some kind of result.

Once a workable direction is found, the final result that gets sent to
the list could be a clean-room implementation written by the human, it
could be fully written by an agent, or anything in between.

And finally the human could have reviewed the work end-to-end,
line-by-line; delegated it all to a review agent; or neither.

The process behind a patch with this tag could be anywhere on this
spectrum. And reviewer interpretation of the tag is just as varied.

It poorly communicates what actually occurred. And there is clearly a
stigma attached to it at this point, with the expected consequences,
which further distorts the signal. The latter part might go away if
there was a better protocol to convey the development process.

But I'm not sure it's practical to even try to capture all these
nuances and precise division of labor questions in commit metadata...
