I've seen it advised to periodically release to production with ASAN/UBSAN/TSAN enabled, with the intention that it's only 1/nth of a deployment, and even then, only deployed for enough time to collect instrumentation.

If nothing else, I appreciate the advisement that it can have security implications.
If you leak all the secrets 1% of the time, that's not leaking 1% of the secrets. All of the secrets have been leaked, albeit over a short stretch of time.
