I do not have a strong opinion here. It is certainly useful to build setiud binaries with sanitizers, for testing. It is very convenient to simply build everything with asan/hwasan, without cherry-picking, like we do in Android for memory testing, but with understanding that there are security holes.

We've got ubsan_minimal runtime library that is half way between trap mode and a full sanitizer runtime, developed with security in mind.

If there is no viable plan to make sanitizer runtime production-level secure, then maybe we should err on the side of usability.
