Pointless and totally ineffective. I cannot change developer habits.
Those who care about their code will document.

Besides, Fedora Core is totally schedule driven. Documentation bugs
are considered critical and do not hold a release. Using FC5 release
notes as an example. Under the  heading "Latest Release Notes on the
Web",  http://docs.fedoraproject.org/release-notes/fc5/ , it states
"These release notes may be updated." Truth is it does not happen. Not
for a free product with a 18 month life span.

If a hook is available then why wouldn't/shouldn't options for
installonlyn appear? Here's what appears:

# yum --help
Loading "installonlyn" plugin
usage: yum [options] < grouplist, localinstall, groupinfo,
localupdate, resolvedep, erase, deplist, groupremove, makecache,
upgrade, provides, shell, install, whatprovides, groupinstall, update,
groupupdate, info, search, check-update, list, remove, clean,
grouperase >

options:
  -h, --help            show this help message and exit
  -t, --tolerant        be tolerant of errors
  -C                    run entirely from cache, don't update cache
  -c  [config file]     config file location
  -R  [minutes]         maximum command wait time
  -d  [debug level]     debugging output level
  -e  [error level]     error output level
  -y                    answer yes for all questions
  --version             show Yum version and exit
  --installroot=[path]  set install root
  --enablerepo=[repo]   enable one or more repositories (wildcards allowed)
  --disablerepo=[repo]  disable one or more repositories (wildcards allowed)
  -x [package], --exclude=[package]
                        exclude package(s) by name or glob
  --obsoletes           enable obsoletes processing during updates
  --noplugins           disable Yum plugins


With the exception of enabling or disabling all plugins the plugins
are totally isolated from yum.
