I couldn't find a document stating that $basedir is deprecated, but I think
you are right in the sense that the project prefix is used for everything
related to the POM of the project (I think in previous versions the (now
deprecated) prefix was `pom` and both the `version` and `basedir` properties
are "built-ins").
We use $basedir in other places as well.
