YAML Variables replaced with separate property definitions

[dmitrijkiltau]

Upgrading from Neos 8.3 to 9.0, Rector replaced the YAML “variables” (forgot how they are called) with separate property definitions. When I reset them, everything seems to work as expected. Should I use the separate definitions or is this just a missing recipe in Rector?

Thanks for the report, this will help us to make the process smoother for everyone!

Those are Anchors and Aliases if I'm not mistaken.

Personally I would use NodeType Presets rather than these (IMO not very readable) YAML features. But: It should be possible to support them and you could help us a lot if you were willing to open a PR with a (failing) test (along the lines of https://github.com/neos/rector/blob/main/tests/ContentRepository90/Rules/YamlDimensionConfigRector/Fixture/SingleDimension1.yaml.inc) that demonstrates the wrong behavior

Thanks for your report @dmitrijkiltau. I know and understand the issue. But I'm not aware of any PHP YAML parser, that supports preserving references.
