Generally, I don't disagree, but not all producers are LLVM. And JS inlining is driven by dynamic heuristics, speculatively inlining likely candidates, whereas statically-compiled C++ code generally doesn't have speculative inlining. So a Wasm call_indirect will not get dynamically optimized into a guarded inline.
