I was suggesting the following idea:
The underlying package graph is actually a DAG, so by splitting modules it is
possible to achieve a state where the module graph also becomes a DAG.
The exact heuristic or algorithm of splitting was not defined.

One idea which is quite cloes to my heart is to make a one package per module
rewrite, with possibly some grouping modules for convenience on top, but that
was determined not to be feasible performacewise at the time.
