Walter Bright:
What little remains is often @system for performance reasons, where you'd turn off a sanitizer anyway.
You are wrong. Both integer overflow sanitizers and those various modern memory/address sanitizers are not meant to be used in the final release of the code. They are meant to be used one at a time during testing or debugging (and the memory sanitizers slow down the code 2-3 times, so they can be used in many cases of debugging), and then later disabled.
