1. These are all transitive dependencies, i.e. dependencies of dependencies (of dependencies). Not much we can do to resolve them. jest is the biggest culprit.
2. We should replace tslint with eslint, which avoids the typestrict dependency issues.
3. All of these dependencies are dev dependencies, so only impact ongoing maintenance, and not consumers of joiful. The only runtime dependencies of joiful are joi and Node.js itself.
