I would like to provide variant specific KSP arguments. For example, I would like kspDebug and kspRelease to have different arguments.

An example use case is Room or DeepLinkDispatch. Both are kotlin symbol processors which write output to a directory. The directoy must be task specific so that kspDebug and kspRelease do not write to the same directory. Two tasks which write to the same directory disable up-to-date checks and caching in Gradle because the build becomes non-deterministic.

For reference, Java annotation processors and KAPT both provide a way of passing task specific arguments to the annotation processors.
