Answer
Each CRD adds endpoints, conversion, validation, and storage overhead on API server and etcd.
Quick Answer
Each CRD registers new API endpoints and type schemas with the API server. The API server must maintain OpenAPI schemas for all CRDs, validate all objects against them, and serve discovery documents listing all available types. Hundreds of CRDs from many operators add significant memory overhead to the API server and slow down discovery endpoint responses.
