Zero defaults to "true" for that flag, meaning the flags are still coupled. But there is not actual coupling: Zero delegates all this work to VM code, which handles everything correctly.

runtime/CompressedOops/CompressedClassPointers.java
java.lang.RuntimeException: 'Narrow klass base: 0x0000000000000000' missing from stdout/stderr
