@balrok FYI (you asked about editing YAML on reddit):

With version 4.1.0, you can edit both a YamlMapping and YamlSequence by using the Merged* classes. Short example (adding a key-value paid):

final YamlMapping original = Yaml
    .createYamlInput("key: value") 
    .readYamlMapping();
final YamlMapping edited = new MergedYamlMapping(
    original,
    () -> Yaml.createYamlMappingBuilder()
              .add("key2", "value2")
              .build()
);
System.out.println(edited);

key: value
key2: value2
