Absolutely (well at least for Rust, because for C it's not required for it to compile: the code will compile to some broken garbage that will either crash at runtime, be vulnerable to exploits or burn your hard drive, depending on the mood ;).

I just found surprising to see a core person of Go declaring heap vs stack allocation to be “implementation detail”. Because if it was, that would mean that my carefully crafted zero-alloc code could become full of allocations one day because the underlying implementation changed! Obviously they don't want their users to be afraid of that.
