Health, hunger, armor, XP bar, crosshair: all of it gone. There is nothing else in the pack, so it stacks on top of whatever else you already run.
Works with DynamX, and on every version from 1.12.2 up to 1.21.11.
If you want to toggle elements individually via commands, use Saro's HUD Hide instead.
