What we have done here is that we have added a _new_ variant, which can be used _at runtime_, but contains instrumented classes instead of the normal classes.
However, it now means that for runtime, the consumer has to choose between two variants:

- `runtimeElements`, the regular variant offered by the `java-library` plugin
- `instrumentedJars`, the variant we have created
