This allows integration tests to access dev services config in the same
way you would with a TestResourceManager.

I am using quarkus 2.7, and I am facing the exact same issue with the NativeImageTest annotation (so probably the 2 other as well). It is hindering using the DevServices while maintaining a good testing level of the native build of an application.

Would it be possible to request a retrofit of the fix in at least version 2.7?

(if I look up the source code and changes it seems totally feasible)
