 * The WebSocket subprotocol is not available on the established socket and therefore
 * needs to be checked during the request handling.
 *
 * Additionally, the keep-alive logic _seems_ to be handled by Bun seeing that
 * they default [`sendPingsAutomatically` to `true`](https://github.com/oven-sh/bun/blob/6a163cf933542506354dc836bd92693bcae5939b/src/deps/uws.zig#L893).
