I don't think it's realistic to expect a page load to not make a bunch of requests, considering that you will always have to support use cases involving downloading many small images. Either you handle that by expecting your servers to open a dedicated connection for each download request, or you take steps for that not to be an issue. Even if you presume horizontal scaling could mitigate that problem from the server side, you cannot sidestep the fact that you could simply reuse a single connection to get all your resources, or not require a connection at all.
