True, but my point is that unlike what zaptheimpaler seemed to imply, if you don't see massively parallel downloads in the network tab already, you are not going to see massively parallel downloads just because you get multiplexed streams, and the sites that do see parallel downloads are already for the most part going to do well.

So the real world impact for users is likely to be small:

Lowering the cost of multiple streams will likely give you decent percentage wise improvements on page download times that are already so good that the absolute improvements are likely to be small, and likely minimal to no improvements on the pages that are actually slow.
