      # Some of the referenced steps set outputs conditionally and there may be
      # cases when referencing them evaluates to empty strings. It is nice to
      # work with proper booleans so they have to be evaluated through JSON
      # conversion in the expressions. However, empty strings used like that
      # may trigger all sorts of undefined and hard-to-debug behaviors in
      # GitHub Actions CI/CD. To help with this, all of the outputs set here
      # that are meant to be used as boolean flags (and not arbitrary strings),
      # MUST have fallbacks with default values set. A common pattern would be
      # to add ` || false` to all such expressions here, in the output
      # definitions. They can then later be safely used through the following
      # idiom in job conditionals and other expressions. Here's some examples:
