Did you actually read the post? The author describes exactly why. It's not to filter and dismiss, but it's to deprioritize spending cycles debugging and/or coaching a contributor on code they don't actually understand anyway. If you can articulate how you used AI, demonstrate that you understand the problem and your proposed solution (even if AI helped get you there), then I'm sure the maintainers will be happy to work with you to get a PR merged.

This is very much in line with my comment about doing it to filter and dismiss. The author didn't say "So I can reach out and see if their clear eagerness to contribute extends to learning to code in more detail".
