Actually, this is not what I thought because BBE.Hash is std::optional. Since this is YAML, you should use `||` instead. So we would emit the hash if either the feature is enabled (even if BBE.Hash is zero) or BBE.Hash has value (even if feature is disabled). In the latter case, we don't need to enable the feature value. Please also use `BBE.Hash.has_value()` to disambiguate against value comparison.
