So that commit would still be in history, just as a lie?  Many harnesses
omit LLM attribution anyway these days and those won't get caught.

I don't really have much of a horse in this race but I feel as if we're
trying to protect from the few people who have direct Savannah access and
those should be among the most trusted people who well understand
CONTRIBUTE.  For the rest of the patches that appear on the mailing list,
if one smells like an LLM, it will appear so and not be pushed by a
Savannahnian, right?  This is a lot of fuss for a very low risk among a
trusted group, of which a single one made a mistake.
