Java Generics, Type Erasure, and a conceptual idea: reified generics as a first-class citizen?

Java chose type erasure in Java 5 for valid reasons: binary compatibility, massive enterprise ecosystem, millions of existing libraries. The decision was probably correct at the time. But we're still paying the cost today, and what's interesting is that the modern JVM ecosystem increasingly depends on real runtime type metadata that type erasure originally discarded. Frameworks like Jackson, Hibernate, Spring, Quarkus, Micronaut, gRPC, Kafka serializers, Bean Validation, OpenAPI, and virtually a
