[MariaDB discuss] Re: Repeatable read anomalies

In the end, it is an evolutionary compromise between getting flexibility and performance on the one hand, and sufficiently correct behaviour on the other. My personal opinion is that the success of the database is in large part due to the constant focus on ensuring the flexibility and performance needed by practical use

This makes sense to me. However, something puzzles me. If mysql places more importance to flexibility and performance, aren't there any customers(especially financial fields) greatly complaining the subtle incorrectness of mysql, leading to money loss and business failure ? If there are, is it enough to push mysql team to correct some incorrectnesses that Kyle found ?
