 We would need to extend module output nodes to also mark values as deprecated if the user specified so. Then, the mark should
 be checked where `tofu.EvalContext` is used to evaluate expressions and blocks (i.e. `EvalContext.EvaluateBlock` and
-`EvalContext.EvaluateExpr`). The deprecation mark check must take into account the value of `deprecation-warns` flag

 and also it shouldn't fire if the value is used inside the module, which marked this value as deprecated.
