For `MethodHandle`s `DirectMethodHandle.shouldBeInitialized(Class)` determines whether a barrier is needed or not. It can be tweaked to behave conservatively during assembly phase and report `true` irrespective of whether the target class is initialized or not. (And it can take AOT-inited classes into account as well.) 

(`VarHandle`s use `Unsafe.shouldBeInitialized(Class)` directly.)
