I don't want to go through the trouble of creating a throwaway to test it, but having worked in webdev long enough makes me believe it's possible that restriction is only on the frontend and some well placed curl may sidestep it
I guess so, but who would force it for a dead thread, that the person you're responding to will never see? Maybe they're using a completely custom HN client tbh.
Facebook regularly shows me "posted 2 hrs ago" posts with comments from 22hrs ago. Lemmy changes the "posted X ago" timestamp when somebody edits their own post. Everyone seems to do something annoying with timestamp.
