​That is a shared fear, I guess, since questioning about 'stable' comes
regularly on topic.
nginx guys regularly say you should not fear using 1.7 branch in
production, however these recent days have seen a lot of bugs popping up,
some of them which one could even consider critical (impacting availability
of the Web server). Definitely not what you want in production.

It seems the philosophy behind stable is 'no risk, few changes', thus
experimental stuff will only be backported after public release/testing on
1.7 branch.
Moreover, according to an answer brought 2 weeks ago
<,252312,252329#msg-252329>, SPDY-related
functionalities are not due in 1.6 branch. Maybe 1.8, once 1.7 will be
considered stable enough?

nginx problems do not come from basic well-tested/heavily-used core
functionalities (the ones you use to fulfil a basic Web server job). They
come from new abilities brought in, which might compromise the whole
