I think it's more about how people are using it. An amateur who spams him with GPT-5-Codex produced bug reports is still a waste of his time. Here a professional ran the tools and then applied their own judgement before sending the results to the curl maintainers.
The last time I was staffed on a project that had to do this, we were looking at many dozens per day, virtually all of them bogus, many attached to grifters hoping to jawbone the triage person into paying a nominal fee to get them to shut up. It would be weird if new tooling like LLMs didn't accelerate it, but that's all I'd expect it to do.
I keep irritating people with this observation but this was the status quo ante before AI, and at least an AI slop report shows clear intent; you can ban those submitters without even a glance at anything else they send.
