We've all seen unmaintainable monstruosities in any language. I think maintainability is a subject that goes way beyond language features. But if I were to relate a language feature to maintainability, that would be proper typing, not variable accessibility. Even though it's not enforced at runtime, a Python code base with type hints makes a huge difference in maintainability compared to one without. Of course Java has that by default and it's nice.
