[radical]

A debug build has WasmNativeStrip=false, which would trigger relinking. Without the change suggested here though, it wouldn't, and thus not really have any effect at all.

Maybe for debug build 1. don't set WasmNativeStrip=false; 2. emit a message suggesting that to get symbols the user should set WasmNativeStrip=false?
