I just made the (implied) observation that anyone deploying nginx shouldn't even bother enabling spdy in 1.4 (stable) because effectively nothing will use it anymore. It was something that people who use "stable" software were able to benefit from starting in May 2013, but it is now no longer and won't be again until nginx reaches 1.6. That is, unless spdy/3 is dropped in favor of spdy/4 by then.
(edit: fixed date)
Yours - "So unless someone has the resources to test and deploy unstable web servers, it effectively means you shouldn't bother with spdy at this point."
Mine - "I think it's a fair assessment that supporting experimental technologies requires more engineering resources. Everyone has to do the cost/benefit analysis themselves."
Don't even bother building nginx 1.4 with spdy support or configuring it since no one can use it. From May 2013 until now there was a benefit to end-users. There no longer is.
If you want to provide the speed benefits of spdy to users, you now need to run unstable nginx or mod_spdy.
