Sometimes it’s simpler than you think @almiroshnich please see #1379

Do know that anchors and aliases will not be supported on export. That would require a whole lot more work that I do not see the benefit from.

What you want is to use the JCasC secrets which has support for default values. ${VALUE:-defaultvalue}
