In case of 2.5G connections (I still get 2.5G on a regular basis, e.g. in some specific train stations on my way to work in the morning) it can easily be 800ms per RTT - so 2.4 seconds before you have a chance to request any content.

And no, you cannot really ignore this if you are interested in fostering TLS' adoption in the real world. Every tenth of a second causes a measurable loss in user interest, and in many organizations this metric will drive the decision. We cannot legislate from our ivory tower and expect the world to follow against their (perceived) best interest.
