While this is good to have, its ultimately up to the maintainer for how this should look, wait for someone to reply to this that is maintainer, they may want to word this differently.

I think the maintainers will handle it from here based on this:

You should be fine to close this or just leave it up either way, maintainers really should be the ones to do this...

blueshank, you're not a maintainer. Please let them comment on the PR.

There is ongoing dev discussion about whether this is reasonable enough, or if AI submissions will be outright banned.
