It's true that AOT compilers can get most of the benefits of JIT compilers by leveraging profile guided and link-time optimization. In principle, we could get rid of shared libraries, ship LLVM bitcode instead and statically compile everything, enabling cross-library optimizations - but so far, we tend to not do that...
