I'll add rampant hyperbole to your list of personal attributes. I'm the one who doesn't understand anything even though you don't use or have any use for snapshots, and you also want no one to have them or it'll make developers careless:

And then you propose a ridonkulous snapshot-rollback strategy that would for certain cause major problems if the rollback were actually done, and then use that as fait accompli for why the entire concept of fs rollbacks are stupid. Your arguments are asinine. Your emails belong in a kill file.
