with MSan would be tricky, that's why it needs interceptors.


Correct.


Why?  Large parts of glibc are just another library and not that low-level.
Sure, it is quite a bit of work to disentangle the low-level bits from those that can be instrumented, but so is writing correct interceptors which actually follow glibc behavior and are not merely approximation of the core functionality. (I'm not talking about memset, but high-level things like getpwuid or glob.)
