Review Comment:
Makes sense.
> Provide a single entry point for configuration
> ----------------------------------------------
>
> Key: MNG-7914
> URL: https://issues.apache.org/jira/browse/MNG-7914
> Project: Maven
> Issue Type: New Feature
> Reporter: Guillaume Nodet
> Priority: Major
> Fix For: 4.0.x-candidate
>
>
> Looking at MNG-7772, this should not require any code change, but it's all
> about configuration.
> I propose to load / interpolate the following files:
> * {{${maven.home}/conf/maven.user.properties}}
> * {{${maven.home}/conf/maven.system.properties}}
> Those files would be used to load additional user properties and system
> properties for Maven. In addition to the simple interpolation mechanism, we
> should provide two enhancements using special keys {{{}$\{includes{}}}} and
> {{{}$\{optionals{}}}} which would be used to load additional referenced
> configuration files such as:
> {{ ${optionals} = ${user.home}/.m2/maven.user.properties,
> ${session.rootDirectory}/.mvn/maven.user.properties}}
> Being loaded early when Maven is loaded, those files could reference
> directories to load extensions from:
> {{{}maven.core.extensions.directories =
> ${session.rootDirectory}/.mvn/extensions.xml,{}}}{{{}${user.home}/.m2/extensions.xml,${maven.home}/extensions.xml{}}}
>
> In various places, the maven code could be simplified and offer more
> configuration points at the same time.
