You have just been passionately fighting _for_ ignoring a requirement in TLSv1.0->v1.2 that is extremely reasonable an interop-enhancing requirement. Now you're asking for addition of an obviously stupid requirement that will obviously impair interop. Such obviously bogus requirements are going to be entirely ignored by a number of implementors, and they will get away with it with ease just as the offenders of current requirements keep offending. The bottom line result will be that you're in conflict with rfc2119 and driving the quality of the document into the ground, because it will become more and more difficult to recognize which of the requirements are really important for interoperability, and which are just political junk. -Martin
