1. If you don’t use a language feature in your code, your code shouldn’t pay the cost—no matter what else might be helped, enabled or prevented by that. To this day compilers let entire features like exceptions and RTTI be disabled entirely rather than accept that there might possibly be some costs worth imposing. 2. Binary compatibility and dynamic linking don’t matter at all, and shouldn’t ever be considered in design or revision of anything language-related. 3. All areas of computer science and engineering are open to being a part of the standard library and existing language and standard library authors are the best judges of what should be in the standard and how it should be implemented than anyone else, including platform vendors or subject matter experts.
