Description copied from interface: BundleSplitListener

Signals that the current application should be split into the given primary and residual roots.

Primary roots are the new decomposition of the bundle's work into transform applications that have happened or will happen as part of this bundle (modulo future splits). Residual roots are a decomposition of work that has been given away by the bundle, so the runner must delegate it for someone else to execute.
