summary
GitHub scraping finds about 67,000 CRDs and roughly 56,000 distinct KRM types across two years, with ~136 types inside CNCF projects and a projection of ~1,000 new API groups next year. Common, concrete patterns are Provisioner, Composite, Enforcer, and Claim/Class pattern; ~25% of types act as provisioners, ~60% use schema validation, and only ~1% expose scale. Popular frameworks and projects actually used in the wild include kubebuilder/controller-runtime, Crossplane, Kubeform, Config Connector, and Gatekeeper/OPA.
