We've been playing with this for the keycloak operator here: keycloak/keycloak#21231

Tue SDK currently supports all namespaces mode - if you don't include a namespace annotation on the controllers the OLM bundle works in descoped mode. You need to make sure your informers are written to pick up the right namespaces, of course.
