Description

Per https://maven.apache.org/resolver/apidocs/org/eclipse/aether/util/graph/transformer/ConflictResolver.html and https://github.com/apache/maven-resolver/blob/84a32a866ff27d4df75124074fd925588f4a574d/maven-resolver-demos/maven-resolver-demo-snippets/src/main/java/org/apache/maven/resolver/examples/util/Booter.java

it may be possible to have Maven retain conflicting dependencies like so:

    // uncomment to generate dirty trees
    // session.setDependencyGraphTransformer( null );

This might be faster than what we're doing.

Contributor guide

Research direction
Uncomment the line `session.setDependencyGraphTransformer( null );` in the Booter.java example and run the dependency tree to verify that conflicting dependencies are retained, then compare performance with the current approach.
