I think there's nothing wrong with trying to sell your solution, and I'm skeptical about the "literal hours" that you claim.
The way I interpret this thread is that the PR poster had a certain itch and came up with a vibe-coded solution that helped him. Now he's trying to make that available for others too. The maintainers don't want it because it's too large a PR to review properly and because they don't want to have to maintain it afterwards.
I can totally see both positions.
I was just referring to the fact that - in my opinion - unlike others here, his writing did not appear impolite to me. But you know, that's just me. I thought that he was trying to sell his code, and it's not unusual to get rejected at first, so I can't blame him for trying to defend his contribution. All I'm saying is that I thought he did so in a respectful manner, but of course you could argue that the whole endeavor was already an act of impoliteness, in a way?!
