      Initially, we planned that all multi-document transactions would run at readConcern level snapshot. However, over time the behavior for different readConcern levels within transactions has changed, and we have needed to check the original readConcern level to make decisions, such as what read source to use. It no longer seems to improve simplicity or readability of the code to internally upconvert the readConcern level to snapshot, and it has led to bugs, such as SERVER-40123.
