I don't think this makes any sense. I can see that long delays in public reporting might not be good for the near future, but a year from now all of the easily found stuff will have been found. At some point, everything will have hardened to a certain extent, new things will get scanned before they hit the streets, and the only bugs being found will rely a lot more on somebody's insight than the LLM used to test that insight.
I think people are getting overly impressed/intimidated by tons of bugs being found by LLMs in a bunch of code that hasn't been looked at by more than a couple of people in years, or even at all since it was written. Those are going to run out. There won't be any code left that hasn't recently been looked over by an LLM.
