These sound good, and I've used things like asan and ubsan which do a lot of the same thing. The issue is not everyone's running in a traditional environment where you have the conveniences of things like... an OS.
I sometimes write code for micro controllers, and I tend to wrap all system calls so that I can run the same code on my PC just to get access to better tools. On small hardware platforms its common that you are forced to use C because of the limited resources, so the options are limited.
