In gradle 6.8.x (and most probably before this already) gradle provides an "idiomatic" way to define aggregrations of reports without task-dependencies. This is mainly done using configurations, for an example see https://docs.gradle.org/release-nightly/samples/sample_structuring_software_projects.html.

Expected Behavior

The dokka Task should support this idiomatic way and should (best case) provide some detailed documentation on how to apply this pattern to an existing project.

Current Behavior

The current plugin implementation does not provide a nice and simple way to implement a report-aggregation, without any task-dependencies without a rootProject-build. The plugin does apply this already, but only to the root-project, so there is no real way to construct a project using the idiomatic structure.
