>Is the speed increase to gain from HTTP/2.0 really worth the loss of discoverability and the increase of complexity?

There is some data here: http://www.chromium.org/spdy/spdy-whitepaper

Header compression resulted in an ~88% reduction in the size of request headers and an ~85% reduction in the size of response headers. On the lower-bandwidth DSL link, in which the upload link is only 375 Kbps, request header compression in particular, led to significant page load time improvements for certain sites (i.e. those that issued large number of resource requests). We found a reduction of 45 - 1142 ms in page load time simply due to header compression.

I'm probably biased though since I'm stuck on a slow connection despite living in a densely populated part of the UK. Connections here won't be improving till 2015 at the earliest. I dread to think how much larger the average web page will be by 2015, both in total size and number of requests.
