In some production environments, all modifications are restricted, and
the addition of business-unrelated tools is generally not allowed.
Adding new tools to Linux distributions may require a very complicated
process, as some of them are directly using centos. But kernel upgrade 
is sometimes necessary, so I think a proc file can circumvent many
problems in the production environment.
