New goal, jvm-dep-usage, analyzes the relationship between the products target T produces vs. the products which T's dependents actually require (this is done by observing analysis files). If the ratio of required products to available products is low, then this is a sign that target T isn't factored well.

A graph is formed from these results, where each node of the graph is a target, and each edge is a product usage ratio between a target and its dependency. The nodes also contain additional information to guide refactoring -- for example, the estimated job size of each target, which indicates the impact a poorly factored target has on the build times.

The graph is outputted into a JSON file, with the intent of consuming and analyzing the graph via some external tool.
