Quarkus without heavy dependencies on Panache?

Question

I like the idea of using JAX-RS in Quarkus as it will make the code not dependent on framework implementation. However when it comes to DB we're proposed to use "Panache" and extend the DB entities from PanacheEntity. I guess it's very handy and good for AOT work (what is basically Quarkus is trying to do) and simplifies Quarkus work a lot, but it introduces heavy dependency on particular implementation and we can't use pure JPA modules because of that.

This conflicts with "clean architecture" and make testing of such DB module complicated [if possible at all]. Let's say i'd like to be able to use the same DB module (using pure JPA annotations only) for both Spring and Quarkus-based app modules. It forces me to duplicate the code or cheat in terms of design purity.

Is there any possibility to use pure JPA annotations for persistence and probably pay the price with plugins (that modify the code during compilations) or by using of ORM framework(s) that do not do runtime bytecode modification/use reflection? Any examples?

PS. Congrats on 1.0 release! Good job, Quarkus team.

Panache is purely optional and you can stick with plain JPA, as documented in https://quarkus.io/guides/hibernate-orm.

If you could explain why you think you have to use Panache, I believe that would be interesting for the Quarkus team.
