If this cannot be a CompletionHandler, probably the other callbacks cannot be either.

I wonder whether ScriptExecutionContext::postTaskTo would be able to prevent these kind of checks in the future.

Since we already expose Connection through getConnection, maybe it is fine to allow iterating in some ways inside SWServerRegistration directly.

> +    m_registrationReadyRequests.append({ topOrigin, clientURL, WTFMove(callback) });

If we want to keep good WK2/WebCore layering, we should probably add this vector somewhere else, maybe at SWServerConnection level.
WebSWServerConnection::resolveRegistrationReadyRequests would also move up there.

In preexisting code, we should probably add an SWServerConnection::matchRegistration that would return an optional so that we would do less WebCore stuff in WebSWServerConnection::matchRegistration.
The same could apply there as well maybe.

> Source/WebKit/WebProcess/Storage/WebSWClientConnection.cpp:158
> +void WebSWClientConnection::whenRegistrationReady(Ref<SecurityOrigin>&& topOrigin, const URL& clientURL, WhenRegistrationReadyCallback&& callback)

Could probably take a const SecurityOrigin&.
