Currently, 3 options are implemented: - options.prune (defaults to `false`) - Remove null or undefined fields from the object after merging. - options.merge (defaults to `true`) deep-merge nested fields, note that dependency fields are always deep merged regardless of this option. - options.warnIncompatibleVersions (defaults to `true`) Output warning if two dependency version ranges don't intersect. Closes #4779
