Well, not implementing GC isn't really a viable option long-term. You have to have some bridge between Web Assembly and objects defined in WebIDL, and, for better or for worse (I think: for better), GC'd objects with WebIDL interfaces are the COM objects of the Web. If DOM objects can hold on to Web Assembly objects--as for example happens in the case of event listeners implemented in wasm--and Web Assembly objects can hold on to DOM objects, then the only sensible solution to memory management is a GC that can trace both kinds of objects. All other solutions eventually lead to uncontrollable memory leaks (see IE6).
