"I don't see any reason to make a video about it". This sentence is so wrong in its depth that's difficult to know where to start arguing against it.
"The disclosure is to help maintainers assess how much attention to give a PR."
For the same reason we should ask how many years contributing have been writing software and in the specific language, as they are also correlated with quality of produced code.
"we need to be responsible about what we're using it for and respectful to the humans on the other side that may have to review or maintain this code"
Yes, producing great code and documentation, regardless the process.
There's a world of difference between giving feedback and coaching to a human that might be able to learn from that feedback and use it to do better, and giving feedback and coaching to a LLM that has a human acting as its go-between.
If research continues over the next few decades, these LLMs (and other code-generation robots) may well be able retrain themselves in real-time. However, right now, retraining is expensive (in many ways) and slow. For the foreseeable future, investing your time in providing feedback and coaching intended to develop a human programmer into a better human programmer to an LLM is a colossal waste of one's time.
