It's more about 'feeling' native than actually being native. I managed to reinstall VimFX and it doesn't quite scroll like the arrow keys, either. But its scrolling speed still feels more natural than either Vimium or Tridactyl, although it's a bit slow.
Tridactyl's huge jumps are annoying to me, as is Vimium's excess smoothness. In Vim, I hit j once to scroll one line, same as <down>.
