Buildpack produced image includes the entire source build directory?

[jweaver-personal]

Playing around with the scala buildpack using the pack cli and the produced image in /workspace includes the entire source directory (source code, build artifacts, extraneous directories).

Is this intended? Am I not specifying something correctly?

Shouldn't the image only include the produced jars?

It would be nice to drop the source but it is a bit hard because the buildpack would need to detect the stage task outputs. There may be a way to do this using existing sbt tasks / settings but there is the possibility that something goes wrong due to different versions or something else.
