This feels more like an old problem getting reframed as an AI problem.
people were already diffing kernel commits and figuring out which ones were security fixes long before llms. if a patch lands publicly, the race has basically already started.
also not sure shorter embargoes really help. the orgs that can patch in hours are already fine. everyone else still takes days or weeks.
if anything, cheaper exploit generation probably makes coordinated disclosure more important, not less.
