For anyone using or interested in backstage, and possible integrations with crossplane, ive developed a few useful plugins for this and wrote a small blog post describing the use cases, UX and features. The code is all available on github and any comments, feedback, or contributions are always welcome!
The TLDR is that this enables auto ingestion of claims as components in backstage, auto generation of gitops friendly software templates from all XRDs in your clusters, and crossplane resource visualization similar to komoplane but directly within backstage.
