I think AbstractScopeAwareRector is now ready to be used in custom rector rule, as the next of UnreachableStatementNode is correctly has Scope now, so on this PR, I remove the @internal note comment .

By this, the tweak of PropertyFetch filled outside method which make read after $this->nestingLevel < 2 got UnreachableStatementNode on MultiDirnameRector at PR:

• [Php70] Refactor MultiDirnameRector by moving nestingLevel check to separate method #2488

can be rolled back as it no longer error on running rectify:
