It's not.  Uninstalling a plugin is not exactly a deterministic  
operation and definitely not closely related to or the inverse of  
installing one: installing a plugin unpacks files and configuration  
that you may not want to remove, and also pulls in dependencies that  
may then be used by other plugins.  We should encourage people to  
assemble a new server instead of uninstalling plugins.

Which method exactly are you asking about?  The config store would  
tell you all the plugins that are in the repos known to the server.   
The plugin installer would tell you all the plugins that have been  
installed on this server instance.  These are barely related when you  
are running multiple servers off of one geronimo install.  For an  
example see the plugin farm instructions:
