Count of transitive dependencies that would be required to add when removing an unused dependency

Is your feature request related to a problem? Please describe.

When looking at the buildHealth report, there are a number of unused dependencies that can be removed, and a number of transitive dependencies that are suggested to add directly. For many of our internal libraries that are relatively lightweight, the transitive dependencies are okay to be included in a transparent way, if it means we add a single internal library instead of 15 other dependencies.

Describe the solution you'd like

For each suggested unused dependency to remove, I would like it to include a count of how many transitives from that dependency are used. If the count is zero, then that dependency can be removed no questions asked. If it's 10+, we'd probably just leave it for conciseness of the build file.

Describe alternatives you've considered

I think I saw an issue asking for the "reason" report to include all dependencies in one go - this would also be useful. Running the reason on every dependency one at a time isn't really practical for us.
