Perhaps as a verbose option? I recently wrestled with a build and the problem ended up being that I had removed the version tag and maven apparently chooses the worst version in that case.
I was trying to verify that configuration was propagating properly from pluginManagement to build/plugins. So, I wanted to verify the configuration but also the version number would have immediately clued me in.
Considering how difficult maven poms can be to work with I really don't understand why this type of plan is not built in.
