Please see NEWS.Debian.gz and /etc/vim/vimrc which have similarly worded
descriptions of this:

  " Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
  " This happens after /etc/vim/vimrc(.local) are loaded, so it will override
  " any settings in these files.
  " If you don't want that to happen, uncomment the below line to prevent
  " defaults.vim from being loaded.
  " let g:skip_defaults_vim = 1
