We shouldn't have GC, Exceptions or Tail calls in WASM, as long as the compiler can provide them. I’m not a compiler guy, but spent my time with runtimes closely, and can say that befriending GCs/RCs, exceptions, continuations, etc between them was my least favorite part. That said, wasm is already a potential target for different runtimes built with no common vm in mind, so interop headaches are imminent either way.
