There are two aspects, as I understand it: Graal's native image and Quarkus's compile-time evaluation of annotations. Each is responsible for different aspects of space and time saving. The comparable compile-time effort in Spring is being explored in the spring-init project[0] and I believe will be a core feature in Spring Boot 3 / Spring Framework 6, along with Graal support.
