Make it possible to set default versions for reporting-plugins (i.e. plugins under <reporting>).
dependencies have dependencyManagement and plugins have pluginManagement, but there doesn't seem to be anything for reportPluginManagement.

Could be that I missed out on something, but I doubt it since I stumbled on this issue with aspectj-maven-plugin and it's aspectj-report (similar to javadoc).
The same plugin is used under build and reporting. pluginManagement stated that version 1.0-beta-4-SNAPSHOT should be used, but it was only for build.
Instead 1.0-beta-2 (not snapshot) was used for the report.

This issue came up in the following thread in mojo-user:
