Not sure if there was a merge error, but I noticed this while generating the new resources.

Suggest to add a flag to skip adding the observedState. Some resources have specialties and this could cause confusions

From my experience, I typically decide whether to keep or remove observedState AFTER the types have been generated. Instead of using a flag, it might be simpler to just delete or comment out observedState afterward. Using a flag complicates the workflow: first generate the types -> realize observedState isn't needed -> manually delete the generated files and regenerate them.
