But then they would think twice before furthering "...serves too many interests, and (particularly in the TLS portion of the tree) is a grab bag of functionality" [0] of un-security-like features like heartbeats. They might think: "Do I really want to write tests and a demo for this, or can I make do with something simpler?"
If not, then this suggests a lack of clear guiding principles of what is in-scope and what is not &| insufficient questioning of adding new features.
But that's not an acceptable assessment of leadership for a vital crypto WG, much less the leading implementation. So far, OpenSSL has added one dev and it seems like business as usual. Does anyone know if anything's changed at TLS WG (I'm not on the mailing lists)?
I'm not sure what to tell you. I follow the mailing lists but very deliberately don't post on them, because I would drastically increase the noise level, which is already often bad. I can say that it does not look like the TLS WG has a "default deny" stance w/r/t/ new features for TLS.
I like what Google is doing; they control the Internet's most important server properties and one of the most important clients, and are taking full advantage of that to testbed TLS refinements and then bring them to the IETF as working code.
