Why mvnup is not a plugin of Maven 4.

I have just tried Maven 4.0, and found that there are several commands
provided in the mvn dist, but I am sure the purpose of Maven.

When I used Arquillian and Maven 4 in projects, I encountered some warnings
in the Arquillian archives for Maven POMs when running Arquillian tests.
However, when I clone the arquillian-core repository
https://github.com/arquillian/arquillian-core/, and attempt to run `mvnup
check` and `mvnup apply`, there are no updates.

1. I do not know the purpose of mvnup?
2. Why is it not a built-in plugin in Maven 4 that provides a 'check' and
'apply' goal?

Ideally, there is a built-in upgrade plugin/framework that refreshes the
Maven plugin configuration to the latest version when executing the apply
goal, and every broken upgrade of a particular Maven plugin provides
OpenWrite-like scripts for the upgrade execution.
