We are committed to support for new protocols for all customers. We've rolled out SPDY, IPv6, HSTS, HTTPS (free certs) for all and are close to adding DNSSEC and will add HTTP/2. We're not waiting for these things to gain traction.
To give you an idea of what we are doing and the impact take a look at this chart of SPDY deployment.
There's a sudden increase in sites (a doubling) using SPDY. That's when CloudFlare have every single customer free HTTPS and SPDY.
