maybe you should have a look into the Debian Policy, especially into "Chapter 
7 - Declaring relationships between packages"[1] and 

"Package A recommends Package B, if the package maintainer judges that most 
users would not want A without also having the functionality provided by B."

This is exactly our usecase ... as there maybe users which want to have some 
packages installed, which are needed by nagios-plugins-standard. By default 
recommanded packages are installed automatically[2], so nothing "breaks"! If 
you disable installing recommanded packages automatically, you have to care 
about yourself.

Sorry, cluttering the package into so much packages is wasting disk space 
(e.g. on mirrors, installed systems) and making package maintainance more 
complex without real benefit.

Which isn't a problem, if you want to use some plugins of the nagios-plugins-
standard package, you likely want to install this package and in this case you 
can have a look into this file, if and what package is needed to get the 
plugin working (just in case you disabled auto installation of recommended 
package, if not these packages are installed anyways).

And again, if you didn't touch the package management[1], you don't have to 
care about this as the packages are allready installed. If you have touched 
packages managment, we imply that you know what you are doing and keeping care 
of the Recommends yourself and exactly for this case we have 
"/usr/share/doc/nagios-plugins-standard/README.Debian.plugins" as additional 
documentation for you in place.

Did you ever have a look into
