Love the idea, but just to be the devil's advocate, I think it will just mask garbage videos. Currently, the clickbait thumbnails and titles are an indicator to blacklist a channel, without having to waste time watching it.
If you look at the DeArrow website and browser extension pages, I made sure to only use high quality channels as examples (Tom Scott, CGP Grey) to demonstrate how far reaching the sensationalism problem is.
CGP Grey is personally painful to me. He used to be a no-nonsense education youtube legend, but in the last few years he's just maximised clickability - even going thorugh his whole back catalogue and changing titles and thumbnails.
For example, he made a great video about generative adversarial networks ~5 years ago but now its titled "How machines like ChatGPT learn" - despite coming out before GPT.
Pretty much every successful YouTube channel edits titles. It's just part of the algorithm game now. You will often see videos cycle through several different titles shortly after release.
