Don't worry. If you read carefully the discussion referenced by the last link, 
you will find that "End-of-Life for SPDY/2" postponed to SPDY/4 plus some time.

Yes. And SPDY/3 has no noticeable improvements compared to SPDY/2, but
instead it has some problems. See:

The current plan is to integrate spdy implementation into the nginx code base as 
painless as possible in terms of code reuse and follow-up support.

Work is going on, but that is not related to the patch.
