This isn't some sort of gotcha contest or competition... if you prefer zero then it seems you want a non-lethal game and wouldn't have issues with 5e not being lethal enough. The question then is whether you feel (for your preference and experience playing 5e) that the game skews to high in lethality?
When a manufacturing company has a sign saying X days since last accident, do you think their preferred number of accidents is greater than zero?
I mean, this certainly feels like a gotcha competition, not gonna lie.
