One more possible addition would be to handle the build cache extension handler as seen in the rewrite's own configuration done here:

  develocity {
      buildCache {
-          remote(gradleEnterprise.buildCache) {
+          remote(develocity.buildCache) {
               ...
           }
      }
  }

Great to see! I like how you work around not having a GradleTemplate helper with the GradleParser, and still ensure you use the right indentation.
