This has been proposed before but the file is useful only in cgroup1
which is in maintenance mode and the format has been like that since
forever. Given that there's some chance that it can break dumb
parsers, the choice has been to leave it alone. It's such a dumb file
format to begin with and just leaving it to wither and die seems to be
the right direction.

Thanks.
