I am not sure what the intent is for WASM, but I do know that the intent for XCOFF is to eventually implement the support. I do not see how using an ambiguous message in this commit (when we know what the intent is) is superior to the alternative of having an unambiguous message.

Well, I don't know about "soon"...
Using the WASM message for XCOFF is not actually wrong; so, I can be okay with it.
