I agree to fix false positive reported in #68105. But for capturing in lambda be reference and do forward in lambda, It is just like create a record by ref instead of using forward and do forward in some member function. I don't think it is an expected false positive.
```c++
template<typename T>
void lambda_value_reference_capture_list_ref_2(T&& t) {
    [&t] { T other = std::forward<T>(t); };
}
```

@jcsxky @PiotrZSL Could you think again about this PR?
