My final workaround (read: filthy hack) was to re-define
`__git_complete_index_file` just after sourcing the completion script like:

    # copy __git_complete_index_file to __orig__git_complete_index_file
    eval "__orig$(declare -f __git_complete_index_file)"

    __git_complete_index_file () {
        # options that require 'git' to inspect all files on disk
        local slow_opts_re="(^|[[:space:]])(--others|--modified|--deleted|--ignored|--killed)($|[[:space:]])"    
        if [[ "$1" =~ $slow_opts_re ]]
        then
            return
        fi

        __orig__git_complete_index_file "$@"
    }
