It would be nice to be able to say "compile wasm, but don't JIT JS". I'm not sure what we would call that option. Regardless of what we do, it would:

  - AOT wasm (as always)
  - Compile the wasm thunks at the same time
  - Compile the trampolines that are required for ICs when we compile wasm code (because usually baseline does this?)

I think we might have a super unlikely race in current wasm where it's possible to always be in the interpreter, compile some wasm, and then not have those trampolines either? I'm not sure.
