others if semantic commits are in use.
- Ignore `node_modules`, `bower_components`, `vendor` and various
test/tests (except for nuget) directories.
  - Group known monorepo packages together.
  - Use curated list of recommended non-monorepo package groupings.
- Show only the Age and Confidence Merge Confidence badges for pull
requests.
  - Apply crowd-sourced package replacement rules.
  - Apply crowd-sourced workarounds for known problems with packages.
- Ensure that every dependency pinned by digest and sourced from
GitHub.com contains a link to the commit-to-commit diff
  - Correctly link to the source code for golang.org/x packages
