The above one is where groupId=='maven'.

plugin:install installs it into the local repo, and then into the plugin
dir for maven on execution.

Only plugins in $MAVEN_HOME/plugins are expanded on execution.
The plugins in the local repository are there like all other artifacts,
stored for any other usage that may be needed of them.

plugin:install does this:
<delete verbose="false">
<fileset dir="${maven.home}/plugins">
<include name="${pom.artifactId}-*.jar" />
<exclude name="${maven.final.name}.jar" />
</fileset>
</delete>
<delete includeEmptyDirs="true" verbose="false">
<fileset dir="${maven.plugin.unpacked.dir}">
<include name="*.cache"/>
<include name="**/.processed" />
<include name="${pom.artifactId}-*/**" />
<exclude name="${maven.final.name}.jar" />
</fileset>
</delete>
that *should* remove old versions of the plugin. Are you sure you're using
plugin:install?
Can you provide a test case that doesn't fit the above deletes?
