def loaded_recent_most_version_of?(gemspec)
  # Check if the gem is already loaded via bundler
  # In most cases this is true since all Plugins/Resource Packs inherit from inspec-core

  # follow bundler's original philosophy i.e load gems that are recent most
  # This logic works unless there is a pinned version which we don't expect to have since these are managed by us
