It seems to incentivize the contributor to try our proposing their patch multiple times repeatedly with varied introductory words just to test if the maintainer had a good day to accept the improved code.
The “contributor” doesn’t have the ability to contribute; They do not have copyright over the code so they can’t assign it.
The maintainer should not read it because then they could be tainted and perform accidental copyright infringement in the future.
I find the argument that the act of enforcing rules to protect the things that you want to protect, as the thing that incentivizes someone else to lie, stupid.
If I tell you no, I'm not encouraging you to try to figure out how to get around what I want. Why do you feel saying no counts as encouragement to ignore or evade it?
The hurdle you have to clear as the devils advocate, is what rules is the maintainer allowed to enforce about their repo, and what are those limits. The maintainer doesn't want to introduce LLM generated code. Until you solve for that, nothing else matters.
