It would not. Rust needs ASAN/UBSAN/TSAN/MSAN sanitizers for a reason.

Can you point me to any significant primarily rust codebase that runs sanitizers? I've never heard of that. Unless you mean miri.

Not miri. I mean the actual ASAN, UBSAN, TSAN, MSAN and LSAN sanitizers that are also commonly used in C and C++ codebases. Descendant is the same: LLVM [1]

Not sure what do you mean by that, surely there are. At least the ones who are serious about the development. Sanitizers are part of official documentation in Rust [2].

[2] https://doc.rust-lang.org/unstable-book/compiler-flags/sanit...

No idea what is your point.

The compiler is happy to compile without sanitizers enabled. Why should it require to implement a null check when deallocating when it doesn't when dereferencing?
