Build extensions are loaded too late to contribute event spies, see how EventSpyDispatcher makes a copy of spies when it's created. And even if EventSpyDispatcher didn't make the copy, I think build extensions are not in scope to capture all events, i.e. things that happen before/after individual project builds will not be captures.
What should work is what I call "core extension" [1], which can be configured in .mvn/extensions.xml in your project source tree and are loaded very early during the build, before Maven core plexus container is created.
