Why you're missing out if you're not making Quarkus extensions
summary
Quarkus extensions move work to build time so libraries get faster startup, smaller memory and a richer dev experience; this demo builds an extension that intercepts java.util.logging, adds a CDI interceptor onto JAX-RS @GET methods via an annotation transformer, and ships events with a JAX‑RS client. It uses build steps and build items, the gendex index and a recorder to emit runtime wiring. It targets 300 apps; log prefixing works in the demo, the Minecraft visualization (lightning, chickens) broke due to a client update, GraalVM needs extra substitutions.
