Using an async operation with `io.use()` could lead to the creation of
several instances of a same namespace, each of them overriding the

```js
io.use(async (nsp, auth, next) => {

next();

@darrachequesne Quick question: are you planning on releasing this as 4.3.2? I'm currently monkey-patching socket.io in my codebase, so it would be nice to be able to drop the patch! |
