In Quarkus there is a clean separation between defining classes (or enhancing them) vs actually loading them.

The ByteBuddyProxyHelper we have in Hibernate ORM implicitly forces to load the proxies it generates; this has been shown to come at a performance cost during the build, and since it happens to be unnecessary we should allow to generate such proxies while skipping the class load.
